I think I'm almost there

[Stanzilla]

Ok here's the deal, I have been reading about backing up playstation games for a few weeks. I just got my mod cartridge today so I have been working on this for about 8 hours now. The CD is burning fine, but it won't play. I put an origional game in, turn it on and it boots up to the Game Hunter screen then I take the origional out and put the copy in, a black screen with the word start in the middle comes up and thats it nothing else happens. Once the game started but it was jerky and when it got to the loading screen it stopped. Here is a list of the equipment I'm using;

Game Hunter CD Version MOD Cartridge
SCPH - 1001
Nero 5.0
Iomega Zip CD 650
Imation & Memorex CD-Rs

I am reading the disk at 1x and burning at 2x (Nero does not give me the option to burn at 1x)

Thanks in advance for any help I get.
