The first couple of DVD-5 movies I copied gave me four files in ISO mode. These movies I loaded the .DVD file to burn and these movies work fine. The next two I did Rounders and Undisputed only gave 2 files the .ISO and .MDS files. Both of these movies played 3/4 of the way through and then froze. My question is does anybody know why DVD decrypter only gives 2 files with some movies and if the missing .DVD & .io1 file will make a difference in the playback qulaity of the movie?
