I don't know about you guys but I DO buy pirated DVDs beside the original ones (especially if the title is unavailable at my place). Just wondering, why some of priated DVDs do play on DVD player but not on PC. I notice DVDs with DVD-ROM features could not be played on any PC (DVD drive). Is there some kind of protection code? So far the title I know didn't play is Tomb Raider and Moulin Rouge Disc 2. They just display the file size 0Kb in Windows Explorer.
