Dear Katata-san, Chigita-san, All,

How would one go about this today ?
I mean, how can you best determine the session and track layout of a DVD-R
(or a DVD+R for that matter).

I always liked Read TOC (full TOC, format field 0010b) on devices that do
not support RDI and RTI,
but unfortunately this is not supported anymore on DVD.

What command (sequence) would you suggest ?

Best Regards,
Peter
