Hey Big Papa. I gotta question for you.

you should get in the practice of always using 80 min cds for dc games...thats what i do, and i never have a prob
make your standard 74min=psx 80min=dc that way you wont have a problem, i don't know if it has anything to do with the way different programs make their image files... like cdi images are bigger than iso images for the exact same game..(or visa versa, i don't remember), but the should burn the same.
to be honest i don't have an exact answer other than try a 80 min cd, if you still get a kick out, then it is probably something with the cdi2nero program...it is still in beta, and there are bugs in it, that could be one of them...
