hey all! i've been ripping and backuping dvd's since half a year now. the tools i use are dvdxcopy (for dvd5 disks) and smartripper/dvddecypher + dvd2one + primodvd (dvd9 disks). during this period i've encountered a few dvd's that simply could not be ripped. in fact, they could not be played at all on both my pc dvd drives. standalone playback only... just today, by coinsidence, i bumped into two dvd's that don't allow themselves to be ripped: "This is Spinal Tap" (R1) and "Four Weddings and a Funeral" (R2). both my dvd drives (both region free) can't recognise the previous one. the latter i can recognise with the other drive and smartripper even starts ripping it but jams after 20 minutes of ripping. now i'm wondering, what is it that blocks me from ripping these dvd's? they certainly can't have an excryption too stron for the tools i use? they have no physical scratches or anything either... what gives? any ideas or advice would be much appreciated. feel free to ask for more details. thanks in advance!
