when i play videos on windows media player, it goes out of sync after the 'commercials/break'. the commercials have been edited out and the show cuts straight back in as if there were no commercials. but it seems to only go out of sync after when the commercial would have been. It does this little weird distorted pixel thing for about 2 secs after every commercial too, and then carries on but out of sync. ive been watching these shows for ages but its only recently decided to go all weird. maybe theres a codec that could sort this out?! any ideas?
