Help! Help! I Need Help!

I have a Iomega ZipCD burner and I use
Nero 5.0.3.1 Sometimes when I Copy Games from CD Copy It don't do it right. When I put it in my PSX it won't work. I use Gold Finger. It is a mod chip that plugs in the back of the PSX. I also use Memorex 1x-12x 650 or 700 MB. I hope someone can help me.
