I am basically converting my movie both DVD and Blu-ray to a digital version for my Apple TV.**** I think some of these programs I tried before only extracts stereo audio track but I really need that 5.1 channel. Do you know any program can do that?
Apple TV reads mp4 or mov file format, so you can just rip the dvd/blu-ray movie to mp4 or mov format.
I used AppGeeker for a while, it wasn't that bad, never had any problems with it.
