I just got my hands on one of these buggers, and I'm having a difficult time reading and Detecting +R +RW media. It seems to be ok with -R -RW discs, but I was hoping that it would work easily with both.
The two +R media that I have is the generic Staples brand of DVD+RW and Maxell DVD+RW's
It reads my Sony DVD-R's and Staples DVD-RW's just fine.
Google'ing around, there's not much info on this drive other than specs. It's supposed to support DVD-+R -+RW -+R DL and DVD-RAM. I don't have any DL or DVD-RAM discs to try out.
