the pioneer 108 does and it doesn't. It definately reports that it is once burnt, but the test on some fussy standalone players indicates that something is still wrong here.
i own two old dvd players that won't play dvd-rw or dvd+rw, but they will play dvd+rw if they are bitset using my old Ricoh 6448 dvd burner using the HP bitset utility.
if i burn exactly the same project to exactly the same type of dvd+rw disk on my pioneer 108 using the piodata firmware, then use cdinfo to set booktype to dvd-rom prior to burning, then perform the burn, these disks still wont play in my old players. The dvd info tools all say the booktype have been correctly set, but they still won't play.
It's got me wondering whether there is a burn quality difference between the ricoh and the pioneer models. I have tried Verbatim, imation, and BASF dvd+rw. The ricoh drive will bitset them all and playem in the standalone players no problem.
