Some Help Would be Appreciated...

I have a feeling that somewhere in this board there is a post for this, but I couldn't quite find the answer.

I have backed up games before and they've worked. But I think they were non-dvd games (with black/purple bottoms) I've got a DVD game, and my PS2 is modded with a Neo2.2 from www.mod-chip.com. I use CloneCD and have a DVD-Rom drive. When I go to copy it (the same way I've done in the past) it slaps down some error, and it can't copy. I've also tried CDRWin, but no luck, also an error. How can I backup this game? Oh and another question, can I burn a DVD game onto a CD-R disc? Thanks in advance.
