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 ?
