I am backing up my Diablo II Bonus DVD (came with the collector's edition years back). The DVD is only 30 minutes long, but has about 10 "titles". I'd like to convert this to ONE .mp4 file instead of 10 different small files. I thought maybe the customize/merge option would do it, but that looks like it is only for burning to another DVD, not creating an output file. Anyone know how I can accomplish this?
