I've tried copying 3 audio cd's that are sans copy protection with the new audio cd settings in ccd4 and am getting background noise on the cd. it sounds like interference buzzing. i have an old burner and think that might be it but like i said, these are not copy protected cd's and i have been successful with oter progs (nero, ezcd). I wanted an exact (or near exact) copy and figured ccd was ideal. help!
