Ah yes, rebuilding using $ony CD/DVD Generator is a good way to make cd/dvds more compatible. Its a bit on the "heavy"-end to do tho. (and slightly off this forum ... I dont think we are allowed to talk about it).
Rebuilding using CDgensps2 is "allowed" tho, but u can only do cds. Its a great way way to get your cds runnin' smooth tho, inserting a dummyfile in cdloader, cogswaploader and other "homebrew" cds works really well
