What to do with a non-working CDI (that others have burned successfully)?

I understand the blunt answer, and I guess I failed to mention that I've burned over 75 "backups" successfully with no real problems in DJ. I'm also far from an ignorant "newbie" (just not an expert, either). But it's just been a couple of games that have eluded me - they burn fine, but end up being just "spinning" coasters. I can burn a game just before and just after the problem games - same settings and everything - with no problems. So it's not my DC unit, it's not my burner, and it's nothing else that I can sem to tell. Just these 3-4 games that I've had probs with, and that don't wanna work no matter what.

And if it makes ANY difference at all, 2 of he games in question that I remember are NFL2K2, and Ooga Booga. Don't know if it's anything about those games, per se, but they don't wanna work for me. I think therewere a couple more, but I can't remember which ones (as I *DID* delete them and forget them).

Now, again, is converting the CDI's to another format, and using another burning prog a good alternative to solving a problem like this? Or is there another (better) solution?
