Library keeps corrupting - very frustrating
I'm running the latest versions of SL and iTunes on a 27" iMac. Library is held on an external Drobo running the latest firmware. Solution has been stable for 18 months+ until this started happening this week.
3 times in the last week, the iTunes library file has corrupted. So when I startup iTunes, I get the message that its importing "itunes library.xml". When complete, I am left with a library which has about 20% of total items in it. All movies, podcasts and tv shows aren't showing, so I have to re-add each folder to iTunes to get it to pick them up. Much of my music is also not showing and when I do get everything in, its lost a lot of cover art and has media types incorrectly classified.
The machine and Drobo are powered down properly each night, nothing is just switched off while in the middle of something. I've repaired all volumes with disk utility.
Any idea what could be causing this or what I could do to rectify it please?
I'm also unsure if there's an easy way to backup a few files meaning i can restore the library if this happens again, as so far, each one I try to replace, iTunes seems to initialise it as a new library.
Thanks,
Mike.
I've got the same issues.
Drobo S. OS X 10.7.2. iTunes 10.5
iTunes will not open at all or opens and says iTunes file is damaged and will rebuild. I've tried everything I can think of to do. Repairs, permissions, checks, boot in safe mode, etc. and nothing works.
I'm rebuilding the iTunes file again to see what happens. There is nothing about this in Drobo support.
Anybody coming up with any new info?

Screen Keeps Freezing very Frustrating
Hello,
This is my first time using a forum, from what I have read in other postings, this seems to be the best place to start. I recently had a computer built at a local shop who said they could build me a system with all the bells and whistles I wanted including the ability to watch and record TV. "I was tired of buying off the shelf and Happy with my decision so far" Well, they did except for one problem with the TV@nywhere Master series Card. To defend them they really have done just about everything to get it to work. So I thought I would see If I could find a solution before I have to call them back to fix it and suffer through a detox period without my computer .
I recently received the computer back from the shop and was watching TV when the problem started again. The problem description is as follows: The TV screen seems to lock up or freeze on the monitor and you can still hear the sound even after you force it to shut down; sometimes the TV picture freezes and does not go away. In order to watch TV you have to reboot and sometimes it locks the whole computer requiring a cold boot. At other times it will freeze again while adjusting the settings, as you can see this very frustrating. Any suggestions will be greatly appreciated!
Thank you,
Intel P4 3.0 GHz HT
ASUS P4p800DX MotherBoard
Intel 865PE Chipset

OS XPI agree. I followed some of the links and there is a wealth of information out there. The trick however is to translate that information into something a non-engineer can understand and then apply it to specific troubleshooting actions to isolate the problem to specific components without having to reinvent wheel and sell car to finance the troubleshooting.
Ron, here is what I did, with some recommendations (I would appreciate if the engineers in the crowd correct me if I wander off into uncertain territory):
1. Recommendation: Return the card and get your money back . Read the GlennVidia's signature and buy another video card. If you can't do that or are stubborn enough to want to fix the problem, warning!, you may dig yourself into a hole and end up far away from your original problem. Get yourself a beer and forget about the rest of this post.
2. My first goal in troubleshooting this problem was to try to determine if this was a hardware or software problem. Not necessarily to identify the specific component, but at a very high level to identify the likelihood of the cause being one or the other.
In order to do this you need to create a base line testing environment. Simply power off the computer, power on and reboot. Shutdown all non-essential applications. This should reduce any excess baggage from influencing your tests. I assume that this non-stressed cruising state of the computer is how the tuner card is typically used. I do not expect that anyone would be stressing their computer by watching TV and playing Halo at the same time.
3. If you want to get right to the crux of the matter go to step 4. If you want to see more of what is happening when you run MSIPVS proceed.
There are a number of computer resource monitoring programs available. I use the Motherboard Monitor available at http://mbm.livewiredev.com/. If you install this, you can monitor your processor usage, temperatures, and voltages.
Since most of the work (video decoding) is being done by the tuner, and all we are dealing with is video streaming to the video card, and audio transferred directly to sound card, I would not expect the processor to be overly taxed. You are not using any installed modem, CD drive, floppy drive, the hard drives may in fact have stopped spinning, etc. during the test, so power usage should be at minimum. On my computer the 2.4 GHz Intel processor cruises at about 90% idle when I am running MSIPVS. This does not cause much of a temperature change in the processor or the case temperature which cruises at about 16 degrees C. This doesn't say anything about the temperature of the tuner card and power supply though. The voltages that are shown, I think, are the processor voltages and not the PCI voltages and it may not be accurate to make any inferences here (help me here guys} but my +3.3 voltage cruises at 3.25 V and my +5.00 at 4.89. The most I have seen this varying is + or - .02 even when more resources are being used on the computer. I do not see any unusual fluctuations at or around the time that MSIPVS freezes. This shouldn't be to surprising since almost all of the peripherals are in a stopped state. The system should not be stressed. I have an Antec True Power 380. OK, good brand name, but on first inspection maybe 550 might be better. But then 550 would always be better than 380, but not necessarily the cause of the problem.
4. Here is where we hit the pavement. To prove that hardware is not the problem, all we have to do is get one TV tuner program, to work even under stress, without fail for a reasonable period of time. I mean, we're still using the same power supply, memory, and tuner card, and if they are at fault we should find similar symptoms using other programs. There is a good thread started by Tveith, "Software That Works with TV @nywhere". Ron, try some of the other programs. What I found was that the Intervideo programs, WinDvr3 and Home Theatre, had the same symptoms (freezing picture, wouldn't shut down properly). So here we have same hardware, using same WDM driver, application written by same company (MSIPVS is WinDvr 2), same symptoms. Coincidence? Use any other program on TVeith's list, except DScaler, and you have same hardware, using same WDM driver, and no freezing of picture. OK so maybe its Intervideo code related.
Don't do this at home, DScaler currently corrupts the tuner card EEPROM! I have used DScaler, same hardware, bypasses WDM drivers, no Intervideo code, and have never, ever, had it freeze on me. I have run it continuously for days without freeze up, while stressing the machine running other programs in foreground.
On my machine at least, that strongly suggests that the hardware is not the cause of this problem. Ron, if you try some of these options please post your results. -

How do I get CDs that have been imported into my iTunes library to sync/transfer to my iPhone?? All the material that I purchased from iTunes has transferred just fine, but although the CDs will import to iTunes, they will not sync up with my phone. How do I do this?? I am very frustrated and would greatly appreciate any help.
In what format did you import the cds?
I have never had an issue with this. -

I found my old iPod shuffle (3rd gen) and thought I would sync my iTunes library onto it, iTunes wouldn't recognise it at first so following forums on here I managed to find some apple software to reset and update the shuffle! This worked and the iPod shuffle was then recognised by iTunes but now my laptop no longer recognises my ipad! Very frustrating!
Please can some one help! I've been searching on here for a few days now and have tried numerous suggestions from other people's questions but nothing has worked yet!You can try this:
I am assuming you are running Windows:
Plug in your iPad to the PC.
Now go to "Start" - "devices and printers"
Is your iPad showing there ? (you may have to scroll down)
If you can see it - right click the iPad icon and select "Troubleshoot"
If the USB driver is missing/incorrect it will tell you.

Why can't I tell Siri "No" to stop dialing a wrong number? It's embarrassing to keep telling the same people over and over that I mistakenly dialed their number. Even if I yell "stop" or "no" it keeps dialing. Very frustrating. Even very simple names. And I talk on the phone for a living. Which is why I need to use Siri to save me time. I speak very clearly. Because of this problem, I've had to even add special code letters before people's names to increase the chances of Siri getting it right, which is only about 70% of the time.
That is not a feature of Siri. Submit your feedback requesting such a feature directly to Apple using the appropriate link on the Feedback page:

Note that yelling at the phone does not improve the chances that Siri will understand you. -

Hi there I am having trouble with my outlook express this is the first time it has happened it keeps telling me can't connect to the SMTP server and every password I have tried is incorrect this is for 'iCloud' very frustrating as all our phones are ok
Well I am feeling a bit silly now because that was all I had to do. In the past Workgroup Manager had always opened right up to the list of my users, I never even thought to click on that but apparently that was all that was needed.
I still am not sure how the iChat Server preferences changed themselves on me, but it is not the first time I have had weird "settings" issues with our Snow Leopard Server.

It keeps crashing when I try to play farmville on Facebook. I have tried uninstall & re-install, and everything else that is suggested. My shockwave player is uptodate. I am very frustrated and would appreciate this problem being corrected as soon as possible. I like the Firefox browser otherwise.

melhmmmm, could you tell us what version and hardware you are running? The newer software is starting to get ahead of our older ppc's. It's quite possible that the software is just to advanced and requires an intel processer. Thanks!
