some burning problems

i have a problem , i trie to burn copys from already copied dc-cd,s with dj2.x. Some games will not work like v-tennis or MSR. it keeps giving errors like ecc/edc , or drive failure and no seek complete. other games do work. does somebody know what i am doing wrong?
(p.s. my writer is a plextor 412)
thanx,

I guess your plextor support 'raw read/write mode'.... so don't forget to set this option on during the reading AND burning process...

otherwise it means your burner does not support RAW mode and you can't do anything about that...

I used to have the same error with my old burner : 'CDB Error' near the end of the reading process.

try making an .cdi image of the already copied game. then burn the image.
