Any movie I watch within iTunes (lets say a rental or something I in my library) has the sound go out of sync after a few minutes and it never recovers.

It doesn't seem to be a hardware issue (VLC works fine and even if I moved the movie to the primary drive, an SSD, I still have issues).

Windows XP Pro

    I've similar issues with the iTunes player and it seems to get worse when it plays HiDef clips. I run a GeForce GTX285 1Gig (266.58).

    I can play the same clips in my other video players with no issues whatsoever.

    I run windows 7 64bit, SLI GTX 460 with 4g. PC has 6g of ram and is i7 2.9 ghz. So spec wise its ample. I have tried:

    * Reinstalling itunes
    * Reinstalling the o/s
    * Killing everything and just having itunes play the movie.
    * Running movie and itunes from my SSD (my boot drive).

    So an issue. I wonder if its 64bit related.

    A possibility, but Win7 has superior 32 bit legacy handling when compared to Vista.

    This maybe a software specific issue that Apple needs to address.

    After all, they have yet to roll out a genuine 64 bit version yet.
    The iTunes that was downloaded and installed in my system touted as 64 bit, registers in my OS as a 32 bit.

    Go figure.

    I have the same problem. Any movie I watch within iTunes has the sound go out of sync after a few minutes and it never recovers.

    This was my first download from iTunes. I will not rent anymore movies from iTunes until this corrected.

    When I say an issue with the 64bit build I don't mean the O/S but iTunes as well. I have recently started using it more extensively and so all its weaknesses are coming out.

    I reinstalled iTunes so the library is on the same drive as the iTunes and still have this problem..

    I'm having the same issue - my hardware WAY exceeds the requirements - by 3x- so there shouldn't be any issues at ALL, but there are.


    Possible fixed that I have found are:

         -You can pause then replay the video every few min.

         -QuickTime seemsto play the videos just fine, but you have to track down the files on your harddrive.


    So far, all I can conclude is that Apple wants youto buy one of their computers to solve the problem, but the still haven'tsolved the issue of a.) the majority of the world not using apple computers, b.) pretty muchevery game coming out on windows computers MONTHS before apple computers, and c.) being totallyincompatible with PC's in a business setting. There's a guy who sends files outat my office with his Mac and he is CONSTANTLY redoing things because it isn'tcompatible with other business's computers - its actually really annoying...

    I had the same problem (sound delayed) and fixed it by going to Control Panel->Sound.   Select the SPDIF device, right-click, select properties.  Go to the advanced tab and change it from CD quality to DVD quality.  That fixed the synchronization issue for me.

    Woodrow's solution worked for me as well.  I had the setting at the highest bit rate.  Changing down to DVD quality as Woodrow suggests solved the problem.  Thank you all for the insights.

    Actually -- its only patially improved.  Gets out of sync after about 1/2 hr.  Very frustrating.

    Had the same issue which I suspect originated in a windows upgrade to SP3 for XP.

    Resolved it by updating driver for both video and sound cards to latest versions.

  • jtygsbv Level 1 (0 points)

    That did it Woodrow. Thanks. If you all observe the audio settings for QuickTime ( Control Panel -> QuickTime -> Audio Tab ), the rate is set to 44.1 kHz. So, it seems logical that under the speaker settings you would match that with DVD quality ( 48 kHz which works ) or CD quality ( 44.1 kHz which works as well and matches the QuickTime audio setting's rate ).
