I'd have thought that since AVI files don't store timestamps, there's no other way to tie the video/audio streams together than to sync one to the other (and assume that the capturing process did the same). If you rely on the video/audio samples/sec rates being exact and therefore being able to sync to absolute time, you're bound to drift, because nothing ever is perfect. It's not so much a matter of having a crappy sound card, as having a crappy a/v file format (AVI) that doesn't store timestamps or any other sync information. Could you post your patch? Ben
