For making *exact* copies of a DVD contents (VOBs), no special utiliity is really needed. Just start up a DVD player app, wait for it to handshake with the drive and thereby turn off the protection, kill it, and then just copy the files at will.. The "need" for specialized "ripping" software to make an exact hard drive copy of a DVD has always mystified me.

Now transcoding software.. sure, that's definitely different!
