Hey everyone. i've downloaded the music videos that have been coming up and the Making of Wing Commander III as well as other trailers to the other games just to watch them but after a few seconds or a minute or two, the video pauses and then continues but the sound doesn't stop and what happens is the video ends up being behind the sound so the sync is all off. i think there's something with my codecs but i have no clue how to fix it. anyone able to help with detailed info?
