Newbie RF satellite cables measurement

Hi.
I want to know what tools I need to test rf cables for satellite transmission application. We are experienced manufacturers of data cables and now our clients are requesting us for coaxials cables for satellite transmision, from IF band (70 Mhz) to Ku band (12 to 14 Ghz). I need want to know what I need to ensure that our cables are well made and that they have the needed quality. I'm newbie in RF cables and I don't know what parameters I need to test to ensure that the cable will work and what equipment I need for do that.
Thanks in advance!
P.D. Sorry my poor english

The amount and types of testing performed on your cables can vary widely. A vector network analyzer could be used to acquire full magnitude and phase response of the cable in the specified frequency bands, with limits for magnitude and phase variation depending on the tolerances of the application.
An RF signal generator and spectrum analyzer could be used to acquire just a magnitude response if phase variation is either not important or minimal in the cables themselves. Transmitting data that has been modulated with a phase modulation scheme like PSK or QAM (which modulates phase and magnitude) could make the cables' phase responses more important, thus implying a greater need for testing its phase response.
In summary, the amount and type of testing done on the cables is a technical and business decision. The business decision lies in minimizing test time and capital expenditure on test equipment without sacrificing technical requirements.
Hope this helps.

Newbie question -- charging cable same as for ITouch ??

I bet this is a no brainer --- but: Is the charging (and Sync) cable the same for the iPhone 4 as for the old iTouch Ipod ??
Also, is the charger that I use for my old iTouch the same as for the new iPhone 4, e.g. can i use it as well as the charger socket that came with the phone??
On the other hand -- I have had NO, I mean zero, problems with my iPhone 4 ... no dropped calls, no death grip, no proximity detector problems, no yellow spot on the screen... Mark me down as a very satisfied customer.
DonnieC

Thanks... just making sure... I once burned out a mother board on a computer by plugging into a "different" charger --- so, I am a bit hesitant...
But -- both iPhone and iTouch chargers really just USB connections and therefore equivalent makes sense..

Hardware for satellite or cable streaming

Hello,
We are interested in purchasing FMS and I'm wondering if there is a way we can have our FMS server on a VMWare Host and have some kind of hardware stream our satellite or cable feed to the server?
Thanks,
Dan.

Hi Dan
This thread may have the information that you are looking for http://forums.adobe.com/thread/484725?decorator=print&displayFullThread=true .
But do make sure that you have acquired the rights to re-broadcast the satellite/cable feed.

Sata III hard drive cable compatible with older generation of macbook pro

Would my macbook ( 17 in mid 2009 ) be compatible with a new hard drive cable ( sata III ) ? I upgraded my hard drive to Samsung Pro 840 and wanted to upgrade my sata II cable to a sata III for faster read and write. Is this possible?

Dave The Newbie,
replacing the cable will not increase the interface speed, just as putting racing slicks on a minivan won’t make it a dragster. I have the same model SSD in my Mid 2010 MacBook Pro, and my MacBook Pro’s SATA interface is limited to SATA II, just like yours. Unless you’re planning on mainly running disk-bound apps, it’s not something that you’ll need to worry about — just enjoy the SSD as is.

Is it possible to connect satellite dish directly to Qosmio G20?

Hy everyone,
I have a Qosmio G20-PQG21. The receiver is 60 meters away from laptop position. In this case the channel cannot be changed. The problem this person want to change the channels. The problem is quite simple... can i connect the coaxial cable from dish directly to tv tunner and setup the program guide? or do you have another solution for my situation?
Thanks in advance

Hi
In my opinion its not possible to connect the satellite cable directly to the Qosmio.
You cannot also connect the TV directly with the satellite dish. Its the same case on the notebook. You need a sat receiver between the notebook and sat dish.
There are two possibilities:
1.) You will buy a longer cable from the sat dish to the receiver and place the receiver nearer notebook.
2.) You will place the notebook nearer the sat receiver ;)

Direct Satellite Service radio frequency leakage

I am adding an Airport Extreme Base Station to my system. I recieve internet service via DSS and am cautioned in manual about radio frequency leakage, presumably from satellite cable or the DSS modem. How can this anticipated problem be solved or prevented?

You made me look.. I have never in my life heard of interference on a free license band from communications that is presumably paid service..they are always required to run in a licensed band and pay big money for it to the government.
Looking at the list .. what things should you be worried about..
Microwave ovens.. yes, they do produce interference if the door seals are not good.. stop using it now.. it can hurt you.. wifi cannot.. but I have yet to see this as a major issue.. how much of the day do you have the microwave running.
power lines, railroad tracks, and power stations
You have to be joking.. if you have 250KV line outside your house and it starts to arc.. run for cover. If you run old fashioned CRT monitors.. you will probably go crazy with wavy lines due to the magnetic fields.. but I used to work in an office that ran next to main electrical conduit for a large city.. no problem with wireless.
Railroads.. arcing of lines again..
Power stations.. arcing but do people in those places use wireless.. I suspect so without too much trouble.
Cordless telephones that operate in the 2.4GHz or 5GHz range. Yes, these are real problem.
But it is other people using wifi and all the other stuff in your house using it that is the problem.
I would classify DSS radio along with railway lines and power stations.. in other words if you have problems our lawyers were smart enough to have made sure it isn't our fault.
http://en.wikipedia.org/wiki/Electromagnetic_interference_at_2.4_GHz
This is more the kind of stuff I would expect.. and I see no reference to DSS satellite services. Or broken coax fittings.
This is the quote from Apple doco. To others who are interested.
Avoiding Interference
The farther away the interference source, the less likely it is to cause a problem. The following can interfere with AirPort communication:
Â Microwave ovens Â Direct Satellite Service (DSS) radio frequency leakage Â The original coaxial cable that might have come with a satellite dish. Contact the device
manufacturer and get newer cables. Â Certain electrical devices such as power lines, railroad tracks, and power stations Â Cordless telephones that operate in the 2.4GHz or 5GHz range. If you have problems with
your phone or AirPort communication, change the channel your AirPort Extreme uses, or
change the channel your phone uses. Â Nearby base stations using adjacent channels. For example, if device A is set to channel 1,
base station B should be set to channel 6 or 11.

Wrong cables from tv socket for youview box and tv

Hi there,
I have received my tv box and can not set it up because the cables coming out of my tv socket are two satellite cables (the one with the screws). I have an aerial cable as well. Is there something I can buy to link these cables together or does bt provide this equipment?
Thank you, Alexandra

Unless I'm reading this wrong......
You have a wall mounted faceplate that has satellite screw connections
One serves a sat dish
One serves a traditional aerial
If that's the case, then a male or female (you'd have to check) one of these would do the trick
A satellite to coax converter
You screw one of these in to the wall mounted plate and plug a coax cable in to this.

Advice on cabling - help much appreciated!

Hi, my first post here.......... Im wondering if anyone can help/advise I have had sky for about a year and the tv is in one corner of the room with the sky connected through a cable in the wall to the dish outside. The engineer did all this when he fitted the sky dish I am wanting to change my sitting room around - move the tv to the other side of the room BUT the sky cable wont be long enough to do this at the moment Can I replace the sky cable myself with one that is long enough or do I need to contact Sky and book an engineer to come out to either extend the cable or replace with a new one that is long enough to enable me to move my tv? Not sure if that makes any sense at all but I am hoping it does! Any advice would be greatly appreicated thank you in advance

Test the extension cables hooked up to the Sky box before you start moving the furniture. This is to make sure your signal levels don't drop off to below threshold level when you add the new cables. Amazon do complete satellite cable extension kits.

Coaxial cable for new build installation

Hi folks, We are waiting on the completion of a new build and as part of our list of requests of the developer they have agreed to fit Sky TV cables for us while they are doing the rest of the first fix. We were invited round yesterday to view the work so far and it looks like they are fitting two runs of their standard coaxial cable rather than the "shotgun" type satellite cables that we're used to Sky installers fitting. Will this standard coax be suitable for HD and be future proof against UHD broadcasts? Many thanks!

It really depends on what type of coax it is. For best results it should be WF100 coax cable or its equivalent (foam dielectric, with both copper braiding and copper foil screening). Sky use 'shotgun' WF65, I believe.

I am having a data excess usage issue with my Jetpack although I did not use the VZW network at all.

Background: My home does not have access to landline internet and I am relying on a Verizon Jetpack device rather than satellite cable for internet access. Within my JetPack wireless network I have several devices connected, iPADs, PC’s, printer, etc. (up to 5 devices can be connected with my system). Recently, I had one device within my immediate wireless network that I needed to transfer data via FTP to another local device within my immediate network. The receiving device FTP’d data from device (198.168.1.42) to local IP (address 192.168.1.2). To understand the data path a Trace rout for this transfer is 198.168.1.42 (source) to 198.168.1.1 (Jetpack) to 192.168.1.2 (receiver). Note that the VZW network ((cloud)/4G network) was NOT used in this transfer nor was any VZW bandwidth used for this transfer (of course less the typical overhead status/maintenance communications that happen regardless). Use of the VZW bandwidth would be something like downloading a movie from Netflix, (transferring data from a remote site, through the VZW network, into the Jetpack and to the target device). I also understand if ones devices have auto SW updates that would also go against the usage as well. I get that. My understanding of my usage billing is based data transfer across the VZW network.
Now to the problem: To my surprise I was quite substantially charged for the “internal” direct transfer of this data although I didn’t use the VZW network at all. This does not seem to be right, and doesn’t make much sense to me. Usage is should be based on the VZW network not a local Wi-Fi. In this case, Verizon actually gets free money from me without any use of or impact to the VZW network. Basically this is a VERY expensive rental for the jetpack device, which I bought anyway. Considering this, I am also charged each time I print locally. Dive into this further, I am also interested in knowing what is the overhead (non-data) communications between the jetpack router and devices and how much does that add up to over time?
Once I realized I was getting socked in bandwidth, as a temp solution I found an old Wi-Fi router, created a separate Wi-Fi network off the Jetpack, but the billing damage was already done. Switching each device back and forth to FTP and print is a hassle and there should be no reason the existing hardware couldn’t handle this and charges aligned with VSW usage. Is purposely intended by Verizon? Is this charging correct? And can I get some help with this?
Logically, usage should be based on VZW network usage not internal transfers. All transfers between IP addresses 192.168 are by default internal. Any data that needs to leave the internal network are translated in to the dynamic IP addresses established by the VZW network. That should be very easily detected for usage. In the very least, this fact needs to be clearly identified and clarified to users of the Jetpack. How would one use a local network and not get socked with usage charges? Can one set up a Wi-Fi network with another router, hardwire directly from the router to the Jetpack so that only data to and from the VZW network is billed? I might be able to figure out how to have the jetpack powered on but disable the VZW connection, but I don’t want to experiment and find out that the internal transfers are being logged and the log sent after the fact anyway once I connect…. A reasonable solution should be that users be able to use the router functions of the Jetpack (since one has to buy the device anyway) and only be billed for VZW usage.
Your help in this would be greatly appreciated. Thanks

i do not have a backup of it, so i am thinking about replacing my old hard drive from the water damaged into this one, not even sure if that would work, but it did not seem to be damaged, as i recovered all the files i wanted off of it to put onto this mbp
the previous owner didnt have it set to boot, they had all their settings left on it and tried to edit all the names on it, had a bunch of server info and printers etc crap on it. i do not believe he edited the terminal system though--he doesnt seem to terribly bright(if thats possible)
tbh i hate lion compared to the old one i had, this one has so many more issues-overheating,fan noise, cd dvd noise
if you need screenshots or data of anything else as away
[problem is i do not want to start from scratch if there is a chance of fixing it, this one did not come with disks or anything like my first. so i dont even know if i could, and how it sets now i am basically starting from scratch, because now all my apps are reset but working, i am hoping to get my data back somehow though, i lost all of my bookmarks and editing all my apps and setting again would be a pain

MSI TV@nywhere MASTER PCI TV Tuner card FAQ

So you’ve just decided to add a MSI TV@nywhere Master card to your PC, you’re gonna need some help installing it then!! Before you continue, I recommend you download the Unofficial New Drivers in the other sticky, to avoid any heart (and brain!) ache.
For best results also, you should be running at least DirectX 8.1. This is included on the driver CD, or you can download the latest version from Microsoft's DirectX Page. If you have a P4 which supports Hyperthreading, you will also need at least Windows XP SP2, otherwise you will have to disable hyperthreading in BIOS.
You should also be in the habit of having the latest drivers for your video card, audio card and motherboard chipset; this can also avoid any future TV software failure. And make sure you regularly run Windows Update (or use the Automatic Update feature) to keep your Windows clean and up-to-date. And also remember when installing new drivers or software, if the installer suggests you restart the computer then do so, before you install anything else! Drivers not installing correctly are common causes of problems, especially with this card!
INSTALLING THE HARDWARE
I’m presuming you’re familiar with the concepts of building and upgrading PCs, so I won’t go into too much detail on obvious stuff (like “remove the side panel of your case, locate a free PCI slot…”).
Fit the TV@nywhere Master card into a free PCI slot. If you didn’t get one with it, you’ll need a CD-audio lead from somewhere (the thin grey lead). If you have one connected between your CD drive and your soundcard CD-Audio In connector, then use that, any version of Windows after 98 supports digital audio extraction, so it is not needed there now. Connect one end of the audio lead to the 4 pin header on the TV@nywhere card and the other to the AUX input on your soundcard (or motherboard if using onboard). If you are installing the Mega TV Tuner in a Mega series barebones, connect it to the TV audio input on the mainboard to the rear. Don’t worry about using the 3.5mm jack plug lead to connect tv card audio, we don’t need it now, doing it this way.
CONNECTING YOUR TV SIGNAL
Depending on your global location, this may vary. Either way you need to connect either a aerial (ANTENNA) or cable (CABLE) to the CATV connector on the card. Someone will no doubt clarify this for me, but cable is for US-type cable, which doesn’t need a decoder box. Most people will be using the Antenna I’m guessing. Your choice of CABLE or ANTENNA needs to be remembered, you’ll need this later.
You will not be able (or have limited success) in connecting a video recorder or set-top box to the CATV connector. Instead you will need to use the Composite or S-Video connector, and connect the audio source either directly to the soundcard or to the Line-in on the TV card.
INSTALLING THE DRIVER
Don’t use the driver on the CD. Download the latest driver from the MSI download page. If you are a Mega series user, make sure that Windows has been installed onto the C: drive. If not you’ll have to reinstall, and disable the USB controller in BIOS to prevent the card readers becoming the C: and D: drives. This also causes problems later.
I would advise temporarily disabling any anti-virus programs at this point, to avoid any complications.
When you start up after first installing the card, cancel any Found New Hardware wizards that appear. OK, so extract the contents of the downloaded ZIP, and run the PVSSetup.exe file to install the drivers. Once this is complete, RESTART your PC and the drivers will be installed for the new hardware found.
Check in Device Manager, there should be four new hardware listed under Sound, Video and Game Controllers related to MS8606. If you see any with the (?) next to them, you might need to try the card in another slot.
INSTALLING THE MSIPVS TV SOFTWARE
If you wish to use other TV recording software other than MSIPVS then please feel free to do so.
MSI do not make their own software. At least not all the time. MSIPVS is a rebranded version of Intervideo’s WinDVR software, with extra features added such as network streaming for TV@nywhere. Some people love it. Lots of people hate it. Generally most people who have posted here hate it. People who love it tend not to post if they don't have problems. The people that hate it generally mess initial settings up, which can cause problems when they try to change it. The more patient of us will always get it eventually right!
Install the MSIPVS software. Easy as that. Its setting it up correctly that’s the tricky part. Listed below are the main things to look for when performing initial setup. If you are unsure about anything else then read the manual! Only a complete genius would dare install any unfamiliar hardware without having the manual handy for reference - how do you suppose I learnt anything?
Device
Video Input:
"Device" is always the Conexant Cx2388x Video Capture"
"Source" - select TV if you are connecting your signal to the CATV connector (antenna or cable), select S-Video or Composite if using these instead
"Standard" - set this to your local TV standard, eg if in UK set to "PAL-I". if unsure, do a Google search and find out!!
If you don't set these correctly you won't receive any channels and/or they will appear incorrectly.
Audio Input:
"Device" will be your soundcard or onboard audio device
"Source" will be the connector your TV card audio output is connected to, this will be "TV" on Mega series, otherwise check!! If you connected the internal lead to AUX on your soundcard or mobo, then set it to "AUX". If you used external lead to connect to Line-In, this will be "Line-in" etc etc.
If you don't set these correctly you may or may not hear audio while watching live TV, and you will hear no audio on recorded TV.
TV
Tuner:
"Input" will be Antenna if you have an aerial connected, or Cable if you are connected to unencoded cable TV.
"Country or Region" - if need to explain this one then maybe you shouldn't have this card!
Channel
Now we will see if your settings and TV signal are good! Tick the Freescan box, and then click on Autoscan. This may take a while, and for a short time it may appear that the program is doing nothing. Patience! It will soon start, and then pick up any available channels it can find.
Make sure you have a good strong signal if you are using an aerial, otherwise TV@nywhere won’t pick up as many channels. UK viewers – just using a simple set-top aerial and signal booster, I could even receive Channel Five (or “five” as it is known now!)
So at this point now, if all has gone well, you should be able to watch and record TV on your PC! If it hasn't...

"I've lost my CDs and MSIPVS needs a serial number to install!"
MSI in their wisdom printed the serial key for MSIPVS on the actual CD. This serial key is the same printed on EVERY CD. Which kind of defeats the object in my humble opinion. Anyways, the answer can be found in this post: MSIPVS requires serial number!
"When installing MSIPVS, the program hangs then shows a message saying "remote procedure call failed" "
If you are a Mega user, you have installed Windows onto a partition other than C:. You will need to reinstall Windows, making sure you disable USB controller in BIOS, so that the card readers do not take up C: and D: drives. Upon first restart (after Windows has created partition), you may re-enter BIOS and enable USB controller before Windows continues installing itself.
"MSIPVS installs, but when I start the application I get an error message "WinDVR has caused a problem and needs to shutdown" "
hpkuo credits this to sizzle in his hints and tips thread, but I'll elaborate a little. The problem is caused by QuickTime codecs installed by Nero 6.3.1.15. It is unclear whether later versions of Nero were fixed, but earlier versions should be okay. "A "quick fix" is to rename the files "NeQTADec.ax" and "NeQTVDec.ax" in "C:\Program Files\Common Files\Ahead\DSFilter\"."
Another alternative suggestion is to uninstall the codecs from the registry. I found this solution in another forum for another TV card with same problem:
Go to Start > Run (or press Windows key + R) and enter:
regsvr32 /u "C:\Program Files\Common Files\Ahead\DSFilter\NeQTADec.ax"
regsvr32 /u "C:\Program Files\Common Files\Ahead\DSFilter\NeQTVDec.ax"
The only consequence seems to be that Nero Vision can’t decode Apple Quick time format after this (something I can live with)
If you do require QuickTime codecs to be installed, there is the Quicktime alternative available from here: http://www.free-codecs.com/download/QuickTime_Alternative.htm . Or you could just use an earlier version of Nero.
PS if you are using a non-english setup of Windows, then the above paths will relate to how windows translates on your PC - ie subsitute Program Files etc for your local translation
"I have connected the external audio lead to the Line-In (blue) jack on my mobo, and set it correctly in MSIPVS, but I hear no TV sound"
If your mobo supports 5.1 speakers but only has three jacks on rear, the Line-in and Mic jacks have been configured to act as Rear Speaker and Center/Sub outputs. If you have only two speakers, they should be connected to the green Front Speaker jack. You will need to go into your audio hardware's configuration panel / Windows Audio Device Properties to correctly configure the rear jacks.
The other alternative is to use the internal audio connector - simply use a CD-audio lead to connect it to the AUX or CD internal connector on your mobo or soundcard. CD audio leads (the analog grey lead from your CD drive to the soundcard / mobo CD audio connector) are redundant now, as Windows now uses digital audio extraction through IDE channel. Make sure you set the audio signal correctly in MSIPVS to match this.
"When I start up Windows I can hear a hissing like "static" / the radio is playing"
One issue that was fixed in the latest Drivers; if that still doesn't work then the Radio volume is not muted at Windows startup. I'll let hschroed take over here:
"Both MSI Radio and MSI PVS, unmute the TV card at program start, and mute the TV card at SUCCESSFUL program exit (remember we are not talking about the soundcard mixer state here). What this means is as long as a single program start and a single SUCCESSFUL program exit takes place, the TV card tuner will be muted, regardless of what the soundcard mixer audio source states are. If the PC is rebooted (without a PC power-off), for whatever reason, while the MSI Radio or MSI PVS program is executing (a successful exit has not been performed), the TV card will remain in an unmuted state until the next startup and successful exit of either of the two programs.
The TV card mute/unmute status is carried over a reboot without PC power off. What this means is that after a PC power on, once the TV card has been properly muted by a start and successful exit of the MSI program, the TV card mute/unmute status should be in proper synchronization with the applications (regardless of the soundcard mixer status), as long as the PC is not powered off. (Romulus mentions computer coming out of standby. I did not test that scenario but I would expect that if going into standby means power is stopped to TV card, the effect would be similar to a PC power off)."
"My regular TV receives all 5 channels (even Channel Five!), but when I connect aerial to TV@nywhere I only get 3"
Common to all TV tuner hardware (not just MSI's!) is the need for a good strong signal. A moderate signal might appear okay on a regular domestic TV, but might not be strong enough for the TV tuner hardware. Consider investing in a good signal booster, or getting your aerial changed.
Consequently, I have also learned today that TOO strong a signal is bad for TV tuner cards, as soon as I know more I'll let you know...
"I have connected my VCR to the CATV connector, but it does not appear when autoscanning."
"I cannot receive any channels when I connect my Sky box to the RF (CATV) connector."
Thanks to a wonderful technology called "Macrovision" protection, many VCRs and satellite/cable boxes won't work in this way by connecting them using their RF output. Anyone who gets a result is very lucky. There's always the Composite and S-Video In connectors to try. But either way, the TV@nywhere card won't scan all their channels, you'll still have to change them manually.
"Windows XP Media Center says that my "tuner hardware is malfunctioning or not installed" but I have installed the latest TV@nywhere drivers from MSI"
Neither the Vox or the TV@nywhere cards are compatible with MCE2005. MCE2005 requires an analogue TV card capable of hardware MPEG2 encoding, or a software DVB-T (digital) card that already receives an MPEG2 video stream over-the-air.
You can however still use the Vox or the TV@nywhere using the MSIPVS software outside of the MCE2005 application.
"MSIPVS keeps defaulting my location back to Afghanistan, even though I set it to US / UK/ Sweden / Latvia / Kazahkstan"
You will need to reinstall the drivers and software due to a glitch. Uninstall MSIPVS and the tuner drivers (with its PVSSetup.exe setup program) then restart your PC, and ignore the Found New Hardware wizard. Install the tuner drivers with the PVSSetup.exe program, then restart your PC. Then install MSIPVS, restart your PC and you're good to go again!
"Where can I find these "Unofficial New Drivers" that people keep referring to here?"
The "Unofficial New (BETA) Drivers" became obsolete when MSI officially released them. You can find them on the Product Support page for this card, as they are now the latest drivers. MSI TV@nywhere Master product page

No rebuffering, no “internet service not available”, no waiting for the movie to reload if I fast forward/rewind. And the best part is……. Drum roll, Please rrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr.(cymbol crash)! Fri, 30 May 2014 01:31:59 an email from Verizon Dear Valued Verizon Customer, We realize you have choices when it comes to choosing your Broadband provider, and would like to take this opportunity to say thank you for being a loyal customer and for choosing Verizon. In order to continue to bring you quality service and product innovation, at times we need to raise our rates. Your monthly rate will increase by $3.00 That was all I needed to switch to Charter. So I’m going from $35 a month for slow and many times nonexistent service, to $40 for service that is 10 to 20 times faster, and doesn’t demand a bribe, err, a voluntary contribution from Netflix not to be throttled. And does anyone really believe Verizon position why net neutrality is bad?????

Verizon lobbyists are canvassing Capitol Hill with a curious new argument against net neutrality — it hurts disabled people. BAWAHAHAHHAHAHAHAHAHAHAHAHAHA The sad fact is Verizon, and all of the copper wire providers can't wait to dump you. I also cut the satellite/cable TV plans, as 500 channels and nothing to watch. I live in L.A. and are fortunate to have FREE DIGTAL over the air TV. So I programmed my TV to the 15 stations I only watch, use netflix, or gasp, read a book!!!!!!!!! So, good-bye Verizon. Adious. Zoi geen. Adieu. Annyeonghi kyeseyo. Arrivederci. Auf Wiedersehen. Do svidan’ya.

I know your pain and at least you have the choice to dump Verizon and go somewhere else. I don't have that choice because of where I live Verizon are the only internet providers. I've been having line issues since they moved me over to their "enhanced" service last year. Two months after I was switched my speed began to get throttled down so I called regular support, no help there, then I came here and Executive Appeals took over my case. Man, was that the worst decision ever because they actually made my line worse; constant dropouts began a week after they began working on my line. The original issue was only the throttling, so it went from that to my line being barely usuable but E A refused to fix the problem they caused and stopped talking to me altogther, left me high and dry. Anyway, back I went to regular support and that has turned into a nightmare. No one listens, no cares and now they want to take away the 7.1M that I've had for several years because they think that is causing the dropouts even though I have repeatedly told them that the E A caused the dropout issue and that I never had any major problems with the 7 megs. Sigh, so now on top of still having the throttling issue and dropouts, they want to downgrade my speed. They have had me at 1mbps (as a test) and I still had the dropouts, so I don't understand why they're insisting on lowering my speed permanently when they themselves (MCO) know the lower speed did not stop/correct the dropouts. This has been going on for 10 very long months and I went from having a mostly issue free, good line to an issue filled, bad line...and it continues. This November will be exactly one year since this ordeal began.
Anyway, didn't mean to hijack your post! But I'm glad at least you could leave Verizon and go somewhere better.

Dead imac g4?

Hi there, I need help!
Last week I got a call from a friend because his imac g4 (800mhz - Tiger 4.2) wouldn't start up; it would get to the grey Apple and the spinning wheel and then just sit there. I tried fsck in single user mode, the catalog check failed, same when booting from the installation disc. I ran Mac Test Pro and all the hardware passed, but the test failed again when it came to checking the directory. Booted it up in firewire mode from my own machine, ran disc utility, failed again. Anyway, the upshot is that we did a clean erase and install with Tiger, ran software update, checked everything with Applejack, no problems.
However ... I went round there tonight, saw the maching running fine, my friend was using mail, the machine had been fine all weekend, when all of a sudden, Mail crashed - spinning beachball of death. Tried to force quit - nothing, held the power button and restarted the machine - got the folder with a question mark. Zapped the pram - no effect, tried single user mode - won't do it, tried to open the cd drawer - won't do it (even in open firmware). I took the machine away again and booted it up using my machine in single user mode with the Tiger disc in it:
Ran Disc utility from the Tiger DVD (in my imac G5 in Firewire mode) opened System profiler on the G4 and can see no hard drive in the G4 and no burner - It's as if the Hard drive and the cd drive have been disconnected.
Now I'm still getting the Folder/question mark and can't boot the mac up or open the cd drive.
Any ideas?
All the best,
Kev.
Note, I've also posted this on Mac Fixit.com

Hi again,
just an update and another plea for help. I've tried a few more things, but still get the flashing question mark - zapped the PRAM (again), replaced the battery, checked the harddrive/cd cable, measured the voltage on the battery check points (3.61 vdc), and finally reset the PMU (pressed it only once). Still no sign of the hard drive and open firmware eject cd is still unable to do so.
Incidentally, upon startup, after the chime, I can hear a 'tick tock, tick tock, tick tock' sound, and then I can hear the HD spinning down.
Can I say for definite yet whether the HD is dead or not? And if so, then what's happening to the CD drive?
Any help would be most gratefully received.
All the very best,
Kev.

TV Seasons Artwork Issue

If I'm in the "Shows" view for a certain TV show, it shows the artwork on the right of the episode list, which is nice. But if I click on Season 2, 3 etc, the artwork stays on the Season 1 artwork. Anyone know if this will be fixed soon? Thanks.

Things to know before (and after) installing your TV@nywhere Master card
Quote
"I have connected my VCR to the CATV connector, but it does not appear when autoscanning."
"I cannot receive any channels when I connect my Sky box to the RF (CATV) connector."
Thanks to a wonderful technology called "Macrovision" protection, many VCRs and satellite/cable boxes won't work in this way by connecting them using their RF output. Anyone who gets a result is very lucky. There's always the Composite and S-Video In connectors to try. But either way, the TV@nywhere card won't scan all their channels, you'll still have to change them manually.

DV 16:9 vs FCP vs QT vs iMovie vs iDVD vs "Anamorphicizer"

Hi DV gurus
I know there's a lot of stuff on 16:9 DV available, but I would like to know what is it with QT and 16:9 DV... bare with me...
If I export a DV 16:9 project from FCP to a QT movie with current settings, the resulting QT movie does not display as 16:9 in a 16:9 iDVD project, nor does it display as 16:9 in QT. If I open the file in QT and then 'Export' as DV stream, the resulting file DOES display as 16:9 in QT (why not before!?).
To get the FCP-exported movie to display in iDVD as 16:9 the little application "Anamorphicizer" does the trick, however the reuslting file out of "Anamorphicizer" does not display as 16:9 in QT. What is going on - it's doing my head in...

What is going on is that 16:9 and 4:3 SD are both 720x480 pixels (or 720x576 for PAL) but the pixels are displayed differently when using anamorphic 16:9 material.
This is as a result of widescreen 16:9 tv having to fit into the existing infrastructure of SD tv recording/post-production/broadcasting equipment, and so to make the best use of the available pixels it was decided to use an anamorphic system which is corrected either on broadcast or on reception. You can see the effect of this if you connect a regular 4:3 tv to a dvd player or satellite/cable box and set the dvd/box for connection to a 16:9 monitor. When watching 16:9 tv or a movie on dvd (very few movies on dvd are 4:3) you'll see that the dvd/box won't correct (or morph) the recorded image and will display a 4:3 image instead of a letterboxed one.
Apps like QT and WMV display in square pixels anyway, not SD tv rectangular pixels, but with 4:3 images we don't really notice the difference.
As advised, using the conform aperture setting in QT player will allow you to choose to view the anamorphic material correctly. IT also allows you to view with overscan, which is handy for 4:3 material also.
