OK,so far I've attempted to play a backup of Manhunt and Need For Speed Underground.I'm using DVD Decrypter. Manhunt would get to the main screen and freeze.That's as far as I got with that one.That disc is now a coaster.I found out that I burned it at Max speed.That was probably the main problem with this one. NFS:Underground-I was able to play the game once but that was it.I burned it at 2X speed which I was told is the speed you should burn PS2 games at.After the one time I was actually able to play it,I had trouble with loading time.It was taking forever so I turned the system off. Then,I was having problems getting the Swap Magic disc to load.I was finally able to get it to load,but it's not consistent. To anyone who has a Flip Top.Did you find it easier to get your backup's to work using yout original white lens,or the one that came with your flip top? Any help would be appreciated.
