Problem booting dvd-r's

[acgtavares]

Hi, i've got a AR2v2.2+NEO2.2 and i'm trying to boot dvd-r's.
I do what it says in a manual that i have but when i put the gran turismo 3 codes and then try to select WITH CODES a message appear saying TOO MANY CODES and then AR2 crashes!!! I don't know why this happens, and because of these crashes i cant play any dvd backup. Are there any other boot methods or anything i can do??
Maybe if i download a previous version o AR2 i could boot a dvdr without problems. Does anybody know where i can download it??

I'd appreciatte some help
