I've noticed that too. My copied Simpsons Movie loads instantly, whereas my real ones take almost a minute.
Also, I was wondering why my Futurama wouldnt load. It must have been DVD+R.
Thanks for the info
Actually, MPlayer can play videos from burnt discs without a modchip just fine.
All modchips do is fool the drive into thinking it's a real game, the drive can read burnt discs just fine either way. AFAIK
Mine is just like that, oh and DON'T try to fix it, because the frame is actually attached to the touch panel part of the screen, so taking the frame out will also take the touch panel out, and that's not good.
