I just rendered some video in Vegas 7.0 and when I played it back, it's got this annoying thin, flashing green bar at the very bottom of the screen. This was recorded on a Sony Digital Camera (camera, not camcorder) which usually comes out amazingly well and when I've uploaded in other programs, it plays just fine. I'm guessing it had to do with settings or something? I'm new and playing around with this to learn it, so I don't know a whole lot...

Any suggestions?
