Hey crewz, Curious, i have a Pioneer DVR-109 in a peacee and a DVR-KO4L in my Powerbook. I have this rogue disc, origin unknown, perhaps some disk from Asia i think it has pretty girls on it with no clothes ;-). Anyways when i put the disc in the Powerbook it wont mount and spits the disk out. I put it in a PC an the disc spins up, nothing mounts then i think either the machine will eventually spit it out or just report it cant recognize the disk. This same disk will play an a 75$ set top play with no problems. The inability for these mentioned Pioneer drives have something to do with media compatibility? should i buy a DVD-R from another manufacturer like Plextor with some hope of it reading the disk? I just want to take an image then probably discard the original since its useless to me if it wont work on my powerbook.
