Best dvd ripper on the MAC? Hi all, I run both mac and pc. I am using a program called "ImToo" a dvd rip program on the PC. and been configuring files as iPod compatible mp4 at 620x480 (the only size it will allow for this conversion). But, when I play it on t he droid. I get a thick black border around the entire movie. I also want to control the bitrate. This program can not change from the approx 1250 rate Any better programs? for the MAC in particular?
