Shenmue 2 problems

[kizzycrew]

After figuring out how to get a .cdi into a Nero-useable file (yay me!) I burned it to an 80 min CDR, and yay, i was so happy. I had shenmue 2 disc 1!
So i start the game, watch that nice lil intro, but then, disaster strikes!
As i load up into the 1st area, it comes up with 'data read error in [insert something here].bin!'

The actual .nrg file was 719 meg. Is this what caused this error?
Do I need a 99 min disc thing?
Or is there another way?

My version of shenmue 2 was the echleon one BTW.

Any help is appreciated, I want to finish this game!
