Just bought a Sony DRU 500ax, quick question

[dirtybird]

I currently have a Magic chip installed, but I have a damaged Madden 2003 original game that loads up fine to the main menu, but must have gotten a scratch or something as it freezes when loading up a game.

My question is, A. Can I make a backup of an original of Madden 2003, on DVD? Or is there a limit to which games you can backup on DVD?

B. Even though it is slightly scratched, will I still be able to make a backup of it?

One last question, the burner came with a Soney DVD+RW, can I use that for games? Or do I have to use DVD+/- R's?

Thanks very much!
