it's somewhat debatable as to what gets improved with these new firmwares that just say "match more media". there are many possibilities as to what it means. it could mean that they've readjusted smart-burn speeds for various media in addition to possibly cataloguing more media. sometimes u'll see improvements in read/write quality, and sometimes u won't notice an improvement at all. u can try upgrading, and if it messes up ur drive, u can just flash back.
of course, if u don't have issues with ur current firmware, u don't need to upgrade, and the "if it ain't broke, don't fix it" motto is perfectly fine. however, i'm one of those guys who always has to upgrade, whether i have problems or not. :bigsmile:
