How do I copy? Problems.

[robflack]

I'm having problems making a working backup of my games. I am using nero with a creative drive coupled with a cd rom drive both quite new. I am having problems getting the copies to work in my psx, when i put teh disc in the screen freezes on the playstation logo. I am following all of the instructions that are on megagames.com and making sure all the settings match those on the site.
Does it make a difference if the CD ROM and a CD RW are on the same IDE cable, as mine are? Would it make a difference if i am copying a game bigger than 650 meg onto a 650 meg cd? if so why doesnt nero prompt me? Any suggestions...i'm stressed over it.
