I backed up a movie from DVD+9 to DVD+R using DVD shrink and nero. Every standalone player I have tried, 3 of them, plays the disc fine. But when I put it back in my burner, Pioneer DVR-108 1.19 firmware, it recognizes it as a blank dvd. My girlfriend's dvd drive, some old panasonic drive, won't even read it. I rebooted both computers to no affect. The blank DVD+R's I used are Verbatim 4x discs, and it burned at 4x speed. Is it something I have to with the region of my computer drive? Thanks for any help.
