GTA Vice City Traxdata Backup

[RoX]

I backed up GTA Vice City (NTSC) onto Traxdata DVD. but sometimes i experience loading problems, and in the game i get the "Loading" box, or "cannot read disk"

i have a v4 ps2 (PAL), with a Messiah mod chip.

i have a funny feeling this might be my laser ****ing up, could anyone suggest anything else it might be.

and also, where i could buy a pre-modded uk console, from a company in the uk, that can deliver.

thanks in advance
