Syncing & speed issues on MTP Zen X

I had thoughtlessly 'upgraded' my Zen Xtra 30GB to MTP firmware. Nomadsync doesn't work anymore !!
I am in a big soup now as I use Zen as the primary store of music and do all iD3 fine tuning, new transfers, deletions etc on it through my laptop which does not have any capacity to store music. I backup to my office PC whenever I go there as I have spare HDD capacity .
Forget about syncing ID3 Tags only, all other softwares - (Creative, WMP etc) do not even sync full tracks properly BOTHWAYS.
They do not delete tracks in syncing, nor do they overwrite an older PC track with a newer ID3 edited track from Zen (or vice versa) during Sync.
Notmad appears doubtful as per the info available on their site (syncing does not appear to be important to Notmad) . They have not bothered to reply to my mail.
Strangely, media source has now become the slowest browser amongst all such programs (Explorer, media Monkey, Real) !!
Can any one recommend me a good syncing software?

You're getting some really bad advice from Eddy, who I don't believe for one second is actually an Apple representative. Clearing Safari's cache and twiddling Java preferences won't affect performance for all apps across the board, and zapping the PRAM isn't remotely an appropriate fix for this sort of problem. As to his advice about deleting all your mail, note that I have every message I have sent or received since 2005. You shouldn't keep them all in the Inbox, but telling you to delete them rather than filing them away in other mailboxes is bad advice, and again, wouldn't do anything regarding performance in any program other than Mail.
If you are still having some problems, check your hard drive space. You need to have roughly 10% or more of the hard drive free. Try repairing the hard drive with Disk Utility. I doubt RAM is the issue if you've observed the behavior with only 3 apps open, but just to be sure, open Activity Monitor when things get slow. Go to the System Memory tab and compare page ins and page outs. Page outs should be less than 10% of page ins... if it isn't, you probably could benefit from more RAM. Also in Activity Monitor, look for processes using large percentages of the CPU.
Those are just a few suggestions, post back if you're still having problems.

Bt Infinity 2 Sync Speed Issue

Hi
I hope someone can point me in the right direction after hitting the stonewall which is the offshore BT telephone support.
I have had Infinity 2 for 2 years plus and for the majority of that time the router was generally syncing up at approx. 50-55mb. Over the last six months this has arbitrarily been chopped back to 48-49mb, then 44-45mb and on simply moving the router and powering it back up this week another drop of 5mb to approx. 39mb. Putting a filter direct into the socket today to test that has now made it drop to approx 37mb.
This never seems to remotely recover to anywhere near the speeds I had for a long been receiving.
I have done the quiet line test using the 17070 and it seems perfect to my ears.
The horrendous BT telephone support won't move from the party line of: "your point of line speed was 37mb and we are delivering that so you are within acceptable levels of service for your connection". To the point that the only option they give is to put a formal complaint which I sense is completely pointless.
The data throughput has always been great but is obviously directly related to how fast the router is actually syncing up at.
Have the Home Hub 5 attached at the moment to see the sync stats.
From today:
The router is connected via a BT Openreach master socket. Have tried using a filter direct, changing dsl cables, using the old BT Openreach modem and WAN port. Have even tried a Asus DSL-N66U router which for some reason would only sync up at about 30mb.
Is there anyway to improve the speeds again or am I stuck with the "you getting what we guaranteed at point of sale" line?
Thank you.
Andy

With those speeds, it could be financially advantageous to downgrade to Infinity 1 as your line will not support Infinity 2 speeds, or at least, not enough to be paying the extra for.......

I think my sync speed is stuck or been capped

Hi everyone, last week i had a full line reset because i started dropping in speed, from 16meg al the way down to 9meg, at the time time of the reset my sync speed went to 12.5meg, 24 hours later i was down to 9.494meg down and 1.12 up, im supposed to be on another 10day training but nothing has happened, meaning the hhb3 hasnt switched off or resynced since i dropped to 9.4meg, now after 5 days of constant connection there was still no change so i did a something to try and make my speed drop but nothing happened, it still synced at the exact same speed 9.4meg, im certainly not rate adaptive and i cant have any line issues or my speed would of dropped after constantly plugging in and out the socket and making it resync, so the only things i can come up with is that ive either been capped or the exchange has got stuck for some reason, ive even gone through my entire extension wiring and changed it to cat6, it made my line attenuation lower but no change in sync rate heres my speed test and hub stats.

Thanks for your replys, believe it or not my line as been more stable, meaning alot less disconnects,infact very rare since i last had the snr reset, it auto changed to fast when mods manually reset the snr a month ago, i think it sounds like a joint or something, def not my internal wiring, its all brand new as of today and theres no change in sync so, the prob lies else where, i tried to tell bt before that theres some kind of fault between the pole and the exchange last time my speed dropped when i was on adsl max, it dropped to 300k i think, i rang up for a mac code because they wouldnt acknoweldge the fact and gottalked into adsl2+, everything went well untill 3 weeksago(around that time) i was up to 16meg sync, i posted it on here, after opening my big mouth my speed started to drop so i had a manuall snr reset, that solved it for a while, then i had that bad weather and it all screwed up, like i said previous, about 10-20mins before the reset my sync dropped to 1meg and line attenuation shot up to 65db, after the reset i had 12.5meg, 24 hours later i was down to 9meg, person on the other end of the phone at bt said my minimum sync should be around 12meg

Increase in attainable rates and sync speed

I've noticed that my line is now syncing at 79999 down and 20000up, lasst week, and for the past 6 months the attainable rate has been 60000 down and 15000 up,
I'm still only getting 71000 down via the bt speedtest and 9000up, getting slightly better results on bbc though.
Also noticed my latency to the bbc is down from 25ms to 21ms
have there been any changes to the network or is this the DLM deciding that my line is good enough to handle higher speeds?

I don't think your line will improve even more, as you are at the limit of your package.
If you look at your modem stats you will see both sync rate and max attainable rate. The max attainable rate will only change significantly if something changes in your line. The sync rate will change as DLM thinks fit. If you see your max attainable rate is over around 90000, then maybe you could get more stable sync rate if BT offered a higher level Infinity package.
DLM will always keep your sync rate below the max attainable for stability. For reference, my values are a good but not perfect:
Max: Upstream rate = 23773 Kbps, Downstream rate = 81184 Kbps
Path: 0, Upstream rate = 20000 Kbps, Downstream rate = 73999 Kbps
Down Up SNR (dB): 7.9 14.5
Over the month or so I have been monitoring, my max attainable has dropped slightly, from just over 85000 to values around 82000. My sync speeds have gone up a lot to reach their current appropriate value, because I had had a previous wiring issue that had lowered my DLM.

Drop in Sync Speed

Over the past few weeks I've seen a drop off in the Sync speed of my broadband and the Noise margin increase from 6dB to 8.5 dB.
I was connecting at 6Mbps but now it has dropped to 4.5Mbps - is there anything that I can do to get it back to what it was?
Everything has been fine with the connection itself - it has been rock solid in that it hasn't been disconnecting.

Looks like your target margin has moved from 6db to 9db, this is the values that equates to the initial noise margin needed for a stable sync.
You need to contact the mods on this site (click on one of their profiles for the link to them) and ask to have the targer margin reduced.
They may want to see a period of stable connection first but it is worth contacting them now since it takes them 3 days to reply normally.
A 9db target margin should give more line stability so unless you know what the problem was that caused it to increase (normally a series of resyncs, the default being 10 in 60 minutes) then you may want to check for a line problem first since otherwise if it is set to 6 it may go back to 9 again because of an underlying issue.

Transferring issues w/Creative Zen X-Fi 16gb w/ vista system

<Transferring issues w/Creative Zen X-Fi 6gb w/ vista system I am not computer savvy and do not understand all that computer talk. I can use a pc once the systems are set for me to use. But getting things like this running I have a hard time with. I would greatly appreciate some help.
I need someone to help me with a few things. I have a Gateway desktop pc with vista operating system. I bought a creative zen x-fi 6gb and from day one I have had problems. I think I finally got the firmware to update.
But I am still having a heck of a?time transferring music from centrale to the player. I can only do one song at a time and then after a little while of doing that (like 2 albums later) it stops working. I am doing this using the usb cable that is provided. I don't have the wireless part hooked up yet.
I also had to drag and drop my music into the centrale instead of it updating on its own. How do I fix that?
How do you make a playlist right on the player?
How do I get my calendar info from my yahoo calendar onto the Zen?
I have gone to the creative support site to see what downloads were out there. And I think I am up to date.
Thanks for the help.

All I need to do is open windows media player on my pc and there is a sync tool there that will sync to my zen x-fi? How do I change the folder that the windows media player reads from?
That is my sig (signature) Glad you got it worked out with Media Player.

ITouch Sync Speed to Vista Laptop

If I just connect my Itouch to my laptop and add new tunes via Itunes then the sync speed is very slow. However, if I also connect my old Ipod 30Gb video at the same time to any other USB port the Itouch sync speed increases dramatically! Much faster - almost as quick as the old Ipod. Is this an Itunes issue? It's a bit weird as the old Ipod syncs correctly on it's own. The Itouch has the latest - 3.0 - firmware.

This ABSOLUTELY solved my problem... everyone having hang up problems check this out! It worked perfect. Thanks for the help man... Hope itunes have this fixed soon.

ATV sync speed super stupid slow.

How quickly does it take you to sync one 45 minute TV show from your ATV to your computer? Mine takes me about 45 minutes. Is this normal? If not, how can i speed this up? I have a wireless Linksys router that hasn't been slow transferring files from my MBP to my G5, or any other capacity. If it is the ATV, why does the sync speed blow?

Well, it's new in that it's always been this way since i bought it new. It's just always seemed slow. It took about 2 hours to sync 8 shows from X-Files Season 2 last night. That works out to being about 2.5 GB, but that STILL seems super slow for this network. I have no issues streaming, so i wonder if this length is supposed to happen.
Now, just to be clear, i have a wireless Linksys router (WRT54G V8). I'm pretty savvy re: computers, but i'm a bit weak on networks, so it might not be optimized. I know sometimes my handheld phone can interfere with me streaming to my airport, but only when it is in use.
Otherwise, the router is hardwired to a Comcast modem. Thoughts?

Serious Issues with Creative Zen Vision M 3

This all started when I was fast forwarding through a track and it freezes. So, I did reset and it's in recovery mode, whereas usually it will just restart again.So I tried turining it on and off and was still stuck in Recovery Mode. Tried plugging it into the computer, the computer doesn't recognize it. I did everything the website told me to, but my computer will not recognize that it is plugged into the usb. When I have it docked it will not let me do anything at all. I tried to clean it up and it stays in "scan disk" for hours,I tried to format it, knowing it would erase everything but hoping it would fix, and when I tried to format it, I got a message saying "harddisk problem", when I rebbot it simply reboots back to Recovery Mode and the other option I have is reload firmware, and it prompts me to start updating firmware, but my computer won't even recognize that it is plugged in , in the first place, so I am at a loss with what to do next. The best help Creative can give me is email support. As most of you probably have found out there is no technical support phone number, only for returns/exchanges. I am using Windows Vista if that makes a difference, which it probably does since nothing seems to work on Winows Vista, and when I look at My computer, it shows that the device is present, but yet I can't access it through any media source or when trying to install this firmware? garbage. Any help would be extremely appreciated. Thank you in advance. Sarah

That is just crazy, I am so sorry....Mine was bought just this past June, my boyfriend bought it for me because ipods seem to have really negati've reviews when it came to needing repairs and so on... It hasn't even been a year!! I pasted the st and second email below. I can't believe how frustrating this must be for you. I am still extremely annoyed though, it seems like the only option I have now is to send it in , and god knows how much it may cost to fix it. They really do have some customer service issues. They even elude that no matter if I am under warranty or not there is a possibility of "fees" ARGHHH!!!!

Broadband Speed issue(s)

So, i've been having issues with my broadband speed for around a year and you've sent out 7 engineers to "definately this time, no doubt about it Mr. Ritchie fix it this time" ... FINALLY just over a week ago, the issue seemed to be resolved and i was getting acceptable STEADY sppeds of around 3MB. Last night, to my dismay the issue returns AND my phone line is out of order (constant hi-lo tone) though i am getting a slow/intermittant broadband. I called and their answer was, can you guess? "send an engineer!" ... SERIOUSLY???? You'd think the other 7 previously that said the issue was at the exchange would have been enough?? (or am i being unreasonable after almost a year, 7 Engineers and countless hours being re-assured by someone from India that "it will be fixed definately this time, Mr Ritchie, I understand it must be frustrating..." AARGH!!!

So, i missed a call and received this reply...
"I tested your line today and it's showing a sync speed of 2880 kbps with an IP profile of 2500 kbps, so it looks like that has improved since the weekend. I also checked your line and couldn't find a problem with it at the moment.
Were you having some bad weather when this fault occurred? If the fault is intermittent, it may be related to some bad weather if a joint gets wet."
Yes, the line speed is GREAT during the day, but come 5pm it drops dramatically, especially Ping responce in online games!
The line is back up and running (about 30 mins after i posted); there was some heavy rain, but "joints getting wet", don't Cod Liver Oil capsules get rid of that? ;p
The speed was fixed for a couple of weeks (something about changing me to a new card/profile or something) but now it appears to have reverted back to it's old ways ...
rgds,
Kev.

PETITION: This is what I would like to see in a new firmware upgrade for the MTP ZEN TO

FIXES:
-Ensures correct playback on the player of Zencast audio content that has been transferred using Zencast organiser. Remaining time is displayed correctly, and rewind / fast-forward functions can be used
- Allows users to transfer tracks between folders on the player when using a program such as Creative Mediasource [THIS IS NEEDED FOR ALL MTP PLAYERS]
- Allows charging via USB when the player is not being used by a program or is low on battery [THIS FEATURE SEEMS TO HAVE BEEN REMOVED BY MTP UPGRADE]
ENHANCEMENTS / ADDITIONAL FEAUTRES [I HAVE LISTED THESE BY MY PERSONAL ORDER OF PREFERENCE]:
) Allows the playback of Audible content types ,2,3,4 on the player, via a plug-in in Audible Manager
2) Adds bookmarking feature to the player
3) Adds SmartVolume EQ feature to the player
4) Adds DJ menu to the player
5) Allows user to partition a section of the player for data transfer
6) Allows user to synchronise tasks from Outlook to the player
7) Allows TXT files/ Ebooks to be stored/ viewed on the player
8) Adds BassBoost EQ feature to the player
PLEASE SIGN THIS PETITION TO URGE CREATIVE TO INTRODUCE AT LEAST SOME OF THESE FIXES / FEATURES IN A FIRMWARE UPGRADE FOR THE MTP ZEN TOUCH - also please feel free to add other suggestions that would improve the functionality of the Zen Touch

Speed Issues

Greetings and Salutations,
I'm having speed issues with my Adobe AIR application. From what I've read on the web, AIR is supposed to be fast at drawing graphics. I am writing an application which has multiple screens. On one of the screens I have a tab (SuperNavigator) which has a canvas on it. That canvas has a series of other canvases (built with a repeater) that have graphics in them. I am having speed issues when I have more than 50 of these children canvases. I've tried running it without the graphics (code below is without the graphics) to see how it performs. When I have 954 of these canvases being drawn it takes about 2.5 minutes to draw. This is unacceptable and I'm wondering if this is something I've induced or if AIR was never meant to handle such a large amount of canvases (actually this isn't a large amount, in a real world environment there could be a lot more). I've included relevant clips from the code. There are a couple empty boxes that in the real application will hold graphics.
The class withing the Tab Navigator is a canvas.
In the action Script (the setter line takes 2.5 minutes to get past) (it's binding to the repeater that seems to be my problem).
[Bindable] private
private var _assetList:Array;
[Bindable]
public function get timelineAssetList():Array{
     return this._assetList;

I would appreciate any thoughts or feedback you could provide.

The Canvas is a very heavy object that has lots of overhead. Even worse is the VBox object that is in there multiple times.
What exactally are you trying to accomplish? Just looking over the code, it seems that the same could be done directly with the Graphics API, at a much faster rate.
For each of the VBoxes and Canvases you have, the entire size of each child and parent need to be re-evalulated each time you add or change something. This is a HUGE overhead, and probably why the app is running so slow. You may need to convert this app to use simpler objects (UIComponent or something lower-level like that) to get any speed.
Are you using Flex Bulder? Take a look at the app while the Profiler is running to see what I'm talking about.

Speed Issues Fixed In 9.1.2

Lost all my thumbnails updating to iPhoto 9.1.2 but rebuilding the thumbnail database solved the problem. Best of all, the speed issues are finally gone in iPhoto 9.1.2. Opening the application is way faster again (2 seconds as opposed to 12 seconds or more). Scrolling is way faster again. Can't believe it took this long for Apple to fix this mess. Nevertheless, iPhoto '11 feels like iPhoto '09 once again. Thanks Apple.

Questions and answers on DLM, sync speed and real ...

I was confused about some DML details and posted on a BE forum (https://avatar.bethere.co.uk/forum/viewtopic.php?t=43542) and got what was to me an incredibly helpful response from Tom (drsox). I thought it would be of interest to some readers here so copy it below. Once again, many thanks Tom.
1) FTTC DLM applies only between the cabinet and the modem?
>> Yes, as there isn't any broadband / data signal going anywhere further down the line to the exchange if you are on FTTC!
2) What are the different parameters that apply on this hop? I know there is a current sync speed, a current snr, a target snr and an ip profile. Anything else?
>> The IP profile isn't really related to DLM, it just "follows" your sync rate. In the past the IP profile would take up to 3 days to "follow upwards", leaving you with a high sync and awful speeds! This has been changed now on 21cn and "RE-ppp"ing (rebooting the router) would force the IP Profile to update instantly.
DLM changes the SNR target. So where BE have hard coded / set SNR targets such as 3db, 6db, 9db, 12db etc.. They only change upon user request. BT use their DLM system where line instability or line error counts are collected and analysed, the SNR target and interleaving settings are then modified in increments to try and stabilise the line.
This image shows quite well how, over a 6 day period, BTs DLM noticed that my line fault was fixed. I didn't get the full speed back for a week.
3) Is the ip profile the same as the BRAS profile?
>>Yes
4) The DLM keeps statistics of errors etc to dynamically change the ip profile?
>> Changes the SNR target and interleaving for the line which will reduce the speed, and therefor the IP profile.
5) There is a general theory that the DLM is incapable of telling the difference between an error and a modem power cycle, so that power cycling can cause your profile to lower. Is that correct?
>> Yes, if you resync / power cycle your router multiple times in a day it is likely to try and "combat the line errors" and reduce your sync rate by increasing the SNR and / or interleaving on the line.
6) Can other connections and disconnections have the same effect? For example, if I reboot the router (where this is separate from the modem)? Or use the router interface to disconnect/reconnect the broadband?
>> PPP drops (router reboots while leaving the BT Openreach VDSL modem on and connected) won't affect DLM. The IP profile will match your sync rate upon reconnection of the PPP session.
7) If you have a low ip profile, does this mean that the sync is limited to the ip profile?
>> Other way around, if you have a low sync rate then the IP profile will match the sync rate. If you get an awful sync rate and the IP profile follows downwards, then you resync higher but the router "keeps the PPP session open" (which is possible if you resync quick enough) then your IP profile will stay low, even though the sync is high. Until you reboot your router or disconnect and reconnect the PPP session.
8) Can the sync rate change dynamically without a reconnection? If the ip profile gradually rises, will the cabinet force a resync to make sure the customer is actually getting the benefit of the higher ip profile, or must the user intervene with a modem resync?
>> See above - Sync can rise without affecting the IP Profile and the cabinet does not force a RE-PPP.
8) As I understand it, if the ip profile gets stupidly low for some reason, it can only be reset by BT wholesale? This will only be done after a visit to your home and a telephone call from the engineer to the BT wholesale central admin?
>> Mixed reports plus I don't think people understand the difference between sync speeds, line faults, the delay in DLM increasing sync after a fault.. I expect half the reports on the BT forum are not related to a stuck BRAS / IP profile. It is possible for the ISP or a BT engineer to reset the IP profile and possibly DLM training.
9) (8) This applies to all ISPs using BT Wholesale: some may be more willing to force this process to happen on behalf of their customers, but none can cirumvent it?
>> GEA providers (I believe) still have DLM but don't have BRAS / IP profiles unless they implement their own.
10) Who sets the snr? As I understand it, the customer has no direct control. Is this different for different ISPs?
>> Mixed information again, I believe that BT Wholesale give providers DLM override controls and SNR settings but none? (or few) ISPs use this system.
11) Real download/upload speeds are physically limited by the sync rate. They are also naturally limited by local limitations (such as wireless connections), server limitations, and congestion at various points along the route? Any more? The congestion along the route will vary bewteen ISPs as they use different routes with different capabilitues.
>> It is possible for BTs regional or local cabinet network to become congested. Supposedly the minimum speed you should achieve over the BT part of the network is 15mbps. ISPs such as Plusnet, BT etc.. then layer their own "discriminatory" traffic management on top of that (ie, slow down torrents etc.).
12) Real speeds are 'unnaturally' limited by throttling. This will also vary from ISP to ISP. Sky claims to have none, and BT none except for p2p. PlusNet and John Lewis have significant (but well explained)throttling. All the more expensive operators have none.
>> What you said
13) The ip profile affects the sync rate, and therefore actual speeds. Does the ip profile effect actual speeds in any other way?
>> Not quite right. The IP profile directly affects the speeds you can achieve but the sync rate affects the IP profile. The sync rate is determined by the stability and quality of your line and what DLM thinks it can cope with.
14) Many people (including AndrueC above) report real speeds from speedtests that are consistent and not close to the ip profile. These can't be explained by congestion (that would make them inconsistent). They can't be explained by server limitations, as they are consistent accross servers and the same servers give better speeds to other people. They can't be explained by local limitations, too many people claim sudden drops where the local conditions have not changed. They should not be able to be explained by throttling, as they as seen for many ISPs who do not throttle (I don't hold with the ISP lying theory here). What other factors are there that can explain these cases?
>> AndrueC and some other Sky customers have strange symptoms where speeds are around 20mbps rather than the full sync speed. The only logical explanation is either local cabinet congestion, contention between BT and the provider's network (not enough investment by the provider) or artificial traffic management on the providers side. It is also possible that the router that the customer has attached to their line is unsuitable for the higher speeds. For example an old ethernet router may only be able to cope with 20 or 30mbps! A friend of mine has a TP-Link ethernet router running Tomato on a BT 80mbps service but the TP-Link's CPU limitation causes his service to only perform at around 68mbps; he has a replacement router on order. (Obviously wifi will significantly reduce performance).
15) If you get a stupidly low ip profile, how long can you except it to take before it climbs to something more reasonable? (eg in my particular case, my profile is currently around 15Mb, and from BT service line tests should be around 58Mb). And the classic question, is it best to power cycle the modem (1) never, (2) occasionally (how often) or (3) never if at all possible? Mine did jump from 3.5Mb to 15Mb on one power cycle. Was that just coincidence?
>> My FTTC line took about 6 to 7 days to go from 40mbps to 80mbps after a line fault. It is possible that your 3.5mbps to 15mbps increase was the "re-ppp" affecting the BRAS profile and that your sync had slowly been increasing over time.

what a waste of money sending an engineer to "fix a fault" which does not exist. Precisely.
In my original BE post to which Tom so helpfully responded, I began: It seems to me that DLM is an excellent concept with a highly flawed implementation, both technically and administratively. I think that sending out an engineer to fix an obviously flawed profile is the main example of an adminastrative flaw. I understand (I can't remember source, maybe Tom again) that they are sometimes relaxing the requirement for a visit before reset.
Maybe the DLM system is too keen on stability vs speed. This will keep complaints down from many people: most users won't notice speed too much as long as it is reasonable, but will be upset if their Skype calls and browsing are being interrupted too often.
However, it does lead to complaints from people who notice the drops after an incidence (as in your thread that has drawn lots of interest), or who only get 50 instead of 60. The main technical flaw is that DLM can so easily be confused by drops from loss of power, too much modem recycling, etc, and then takes so long to recover.

How to look at Sync Speeds

Previously on the home hub 2 and BT Total broadband you could look at your up and down sync speeds under the hub manager. Obviously now the connection comes through the openreach modem and then into the home hub. How can i access the modem page to view the sync speed ?

Solved!
Go to Solution.

You can't. It's Openreach kit and the firmware is locked.
The only way to get a rough idea of your sync is from your IP profile which can be found by running a test at www.speedtester.bt.com.
The IP profile is about 96.7% of your sync rate.
