Copy FF7, FF9? Help me understand please.

[binodbdrchand]

Dear all.
I am a recent admittant to CD burning and as expected have run into problems. Here is what I don't get. I already have a FF9 ripped copy(kalisto) that plays fine on my ps1. Now I'm trying to burn it and it just doesn't work. My thinking was, since it was a copy, copying it would be just a question of popping in a cd and burn away. Alas, it seems I'm mistaken. If you could help me understand.

PS. - Same thing happened with FF7.

PPS. - Got Samsung CD - R/RW SW- 212B

PPPS. - I've tried burning with everything. CDRWin, CloneCD, Nero, EasyCD Creator, etc.
