I’ve been playing with my Piodata DVR-108 Christmas present. I burnt a few DVD+R discs and the Piodata drive (1.18 FW) as well as my Toshiba SD-M1712 DVD-ROM drive detect the discs as DVD+R discs with DVD-ROM booktype. My Pioneer DVR-106D (1.08 FW) reports that they are DVD+R discs with DVD+R booktype. I used both DVDInfo Pro and Kprobe2 (media information tab) on all three of the drives for the results listed above.
Can anyone else try a DVD+R disc that has been bitset to DVD-ROM in their Pioneer DVR-106D and see what it reports back as?
