So I'm trying to copy dvd's for the 1st time and having some trouble. I have mac the ripper, and toast, but cant seem to get anything to work. Everything seems ok with toast but for some reason when I insert a blank dvd it just ejects it and says to insert a blank disc. I'm wondering if i bought a bad batch of blank dvd's or if something it wrong with my burner. I have a G4 laptop with a MATSHITA DVD-R UJ-815 Can anyone tell me what I'm doing wrong or what other mac users are using to copy dvd's?
