I've tried everything...I've looked through like every thread!!! I have swap magic 3 plus or something like that!!! I burned my Guitar Hero II with custom songs to a sony DVD-R using DVD Decrypter!!! I get to the load program screen and I swap discs using the slide tool...and I know for sure...I am 110% positive that the tray is locked back in correctly!!! I hit load program and it sits for about a minute then under video mode in blue says "Not a valid PS2 disc"!!! I have tried reburning it using almost all my DVD's (25) also remaking the .iml & .iso files!!! I even tried to make an exact copy of the game without the custom songs and it doesn't work, however it will boot the original GH II disc fine! Also My PS2 is really old I've had it almost since it first came out...the back of the DVD-R's is blue...I heard the PS2 doesn't read well with the blue...could that be my problem!?!?!?! I'm at wits end I've waited for my custom GH II for so long and only to find out that it's not working!!! PLEASE HELP!!! THANX IN ADVANCE!!!
