I've been practicing with conversions (avi to mpeg) and keep getting an odd result. Been using a 20 min test file, but when I convert with tmpg, and then load the mpeg in media player, it just reads as 12 seconds. It will still play up to 20 min, but the timer stops and the bar is all the way to the right. I guess it won't hurt anything when I go to burn, but any ideas on why?
