i capture the video using my ati all in wonder video card, i capture it to either dvd format or avi format. i use media player to pay the avi or power dvd to play the dvd file. but thats not the issue. the issue is that the video plays fine before its rendered and it plays completly fine in the preview window of vegas but after its been rendered in either the svcd or dvd format, it goes out of sync just slightly after about 60% of the video. its the weirdest thing because i only have a problem with captured video. this problem just started, it has worked fine then all of a sudden it started. i have uninstalled and reinstalled vegas, but still the same problem. thanks
