I've got a 2.6Ghz Vaio laptop running WinXP, which I use for playing DIVX videos, among other things.
It worked a treat for about 6 months, then I didn't use it for a couple of months, and now whenever I try to play a video file there are major playback problems...seemingly across all video playing software, all of which worked perfectly before.
Basically, it will play the video without a problem for about 2 minutes, then the video will start to lag behind the audio, getting progressively worse for about 2 minutes, and then the video will speed up until it catches up with the audio. Then it will be in sync for about a minute, then the process repeats.
I'm use the FFDshow codec pack, although it was the same with the tsunami pack, and I've tried the standalone DIVX and XVID codecs, with the same results. IT's not a problem with the encoding of the DIVX's as they worked before, and I've tried it with other files and the same thing happens. It can't be a performance thing - 2.6GHz should be plenty, surely. I've been through and selectively removed active processes, but no change.
The only major change I made to the OS in the period between it working and not was to install XP Service Pack 2. Could this be the problem? I think I've ruled out everything else, but surely other people would have had the same problem?
