How do I know if I use CD-r or DVD-r (NEWBIE)

[Saleen0296]

I have a version 4 playstation and the no-solder chip with Gameshark2. I am a newbie at this so I need to know which CD (cd-r or dvd-r) I have to use with which game. Is there a list that shows which games I have to use a DVD-r. I don't want to "rip" (which I read in this forum) any game. I want to back-up everygame fully. I don't want to miss out on any parts of the game. Is there some Games I can't play even if I copy perfectly? I am currently using the nero burning room program to burn cds. Thank you very much
