I was wondering before I went and tried it if it's better to rip all the files from a dvd to the harddrive first or simply select the dvd itself as the source in dvd2one? That would go faster, but would it work? Is it that the dvd rippers decrypt the copy protection during the ripping process? Also, what exactly are the variable ratio/constant ratio options in dvd2one? I know the compression mode, but what's the difference between the two? Thanks.
