I have no problem with rendering some small 2 minute videos in AVI, they come out fine. When I render in Mpeg-1, I get alot of skipping in the playback in both real player and windows media player, everything stays on beat with the music, it just skips during playback, why is that? I have all of my render settings on the default settings that are installed with Vegas 6. Any suggestions? I am sure my quality output is set to the middle setting.
