I've been trying to rip a dvd to Xvid format with mencoder. I have confirmed that the entire movie is on title 1, but the resulting .avi file excludes the last 20 or so minutes of the movie. here is the code I used...

Code:
mencoder dvd://1 -o movie.avi -ovc xvid -oac mp3lame -xvidencopts bitrate=2000
