PS2 007 Nightfire/GTA Vice City /Tony Hawk 4 Problems

[stevenrandall]

I own a Pioneer DVR A04 Dvd Burner and have been making successful backups of many PS2 DVD games for almost 6 months now. I recently made back ups of GTA Vice City and Tony Hawk 4, and 007 Nightfire. I was also successful in making these copies. I played James Bond, and in the fiirst level the game freezes about 5 mins into the game..As for Vice City..I have been playing this game for months now, and no problems..Just the other day I booted up and had no problems...Once the game starts and I start to walk around the city..It freezes up and says loading...Or I have also seen it say the GTA Vice City Disc is Damaged...The disk is not even scratched at all...As for Tony Hawk...I played the game a few times...Now it wont even load...Game is not scrathced at all also...I am using Apple DVD-R media...I know that is good media...Also..I am not sure what mod chip I have , it is old and I must use a real DVD game (Devil May Cry) along with the Gameshark to boot up my DVD-R backups...I am wondering if the laser on the PS2 is going bad r maybe the mod chip..But my CD-R backups play fine without a problem..Any light shed on these issues could be a huge help!! thanx
