You've probably had this one many times before, so I apologise in advance. Basically, I have followed the your guide for converting .avi to dvd with several files - when I get to the bitrate settings stage, the file length is *always* shown to be about 270 minutes, despite the movie length being only 100 - 150 mins. Obviously this makes the file far too big to burn to dvd. Why is it doing this?! I have checked and fiddled with everything, but to no avail. Help!
