I have CloneDVD 4 by DVDXUtillities and I like the way the program is set-up, I have never really had any problems with copies from this program. What I don’t understand and maybe someone will be able to enlighten me is sometimes under the audio selection section there are up to 4 versions of English (united states) and of those; three of them might be AC-3 format and the other may be DTS. My question is what is the difference between all the different AC-3’s ? And of those if I want to drop off one or two so the movie will fit on a 4.7 GB DVD which ones would be ok to lose. Also the AC-3 is usually followed by a 2 or a 6 to which I have no clue what it means.
