Audio and video playing at different times! 10 points!?

There's no way to explain this without getting a little technical. This is not the same as a Rock Band sync issue, which is simply a matter of processing lag.

Computer movies are generally comprised of a video track and an audio track. Think of it like cutting a deck of cards into a Video ("V") and an Audio ("A") stack and then shuffling them back together. In the original movie, the V and A cards (metaphors for video and audio packets in the movie stream) are shuffled together perfectly and the movie player hums along like a charm.

When a movie is re-encoded and shrunk down, sometimes the cards no longer line up quite right. Where it used to read through 5 "A" cards a second, now it goes through 4.997 of them a second, for instance. When you start playing the movie, it doesn't seem bad, but slowly those 0.003 cards start adding up and suddenly your audio and video are no longer matching up. So you stop the movie and restart it again, perhaps at 45:00 into the movie. When you restart it, the movie player finds the right cards that should play at 45:00 and once again things look correct. But 2 minutes later, the audio is 0.36 seconds out of sync and making things irritating.

I'd mention how your time codes seem right and how that means you might be able to de-mux and re-mux the streams and all to fix it, but that can get a lot more technical than what you've asked for. Your movies are simply the result of someone doing a quick and dirty job of making the video Internet-ready.

I'm not sure there's a low-tech solution for "what to do," but I've tried to at least describe what it is you're running into.

Theres a delay in the sound. A delay happens when the speakers aren't in sync with picture. I don't know how to explain it to someone that isn't farmiliar with the technical terms. I get this problem with my rockband sometimes haha. that's what I think is the problem. It could be the video itself.
