Another possible option is to merge them all later. Somebody mentioned one in my thread, and I used it the other day. It wasn't exactly what he mentioned though, and I cant think of the actual name right now. Anyhow I had a race DVD that I bought which was 4 separate disc's and I wanted to merge them into a single video for easier playback. I ripped the multiple MKV's from each disk, loaded them into the program, and voila a single really long MKV! Its a bit more work that way, but its an option. I wanted to test it out for some of my multiple disc movies (LOTR extended), and seemed to work just fine.
