When I mention in other posts about having audio lag I mean that the video is to early. The lips start moving slightly before the audio starts up. But people always seem to talk about slowing down the audio to fix it. I know its the tv because I don't have the problem when I watch the videos (streaming from internet and video files in avi,mkv,mp4,ect) on the monitor and it still syncs up fine while I watch it on the tv but keep the sound going through the computer speakers. It isn't until I switch the audio over to play through the TV that the off sync occurs.
