I know that some CD burners are more adept at reading certain CD encryptions than other burners. Does the same thing apply to DVD burners? I have never had a problem ripping a DVD with my Lite-On burner, but my friend purchased an EMPREX DVD burner from Fry`s Electronics, and has encountered several ripping problems, apparenty encryption related. We both use the latest version of DVD Decrypter, so the primary difference appears to be the burner. Anybody have any thoughts on this subject?
