Correct me if I am wrong,
but the last time I read something about DVD-R, DVD-RW and so on technologies they were all in a state of flux. There was no standard. I think that Apple's Superdrive is actually the first (or one of the first) DVDs to be compatible with Home DVD players.
Many different companies make DVD-Rs and RWs but each one of them has a different standard/format/capacity.
has anyone got an update on this matter ?
