[QUOTE=Albert;2229569]If the drive burns unreadable DVD-R, the poor burns are not caused by the ‘RPM strategy’ [CLV/CAV and their variants]; they are caused by poor media, a poor burner, a bad combination of the two, or some other computer/user error.
What media are you using? Like HP 16x DVD-R, Verbatim 16x DVD-R, Sony 8x DVD-R, etc.
And in what context is the disc unreadable?[/QUOTE]
I have tried two different DVD-R media till now a Grundig ME153 and a TDK TTH02. The Grundig DVD-R failed verification after burning with Nero and the TDK passed verification with difficulty. Both have PIEs over 300 maximum and very large PIFs, more then 160 maximum on the Grundig disc.
I’m starting to think of a poor burner problem
