I hope it is possible to leave much of this to the drive.

And if it fails ... well, it's only speed setting. :))

ts A70101 : Formatted DVD-RW media. Success is varying with media, but

dvd+rw-format does not do better with the same media.

Determine first free lba for appending data.

Determine start lba of most recent mkisofs session.

MMC-3 seems to recommend MODE SENSE (5Ah) page 2Ah rather than A1, A2, A3.

This page is loaded in libburn function spc_sense_caps() .

Speed is given in kbytes/sec there. But i suspect this to be independent

of media. So one would habe to associate the speed descriptor blocks with

the ATIP media characteristics ? How ?
