hello, I get the same problem. I have a DVD rewriter Plextor PX-716A, and while i put any DVD in it, it's detected like a blank DVD. I can read them only if I insert a CD before. Burning don't work at all. http://www.ubuntuforums.org/showthread.php?t=203949
dmesg report it : "cdrom: This disc doesn't have any tracks I recognize!" Result of cdcaps.py : CDO_USE_FFLAGS returned 13 got drive capabilities: 39ffef CDC_DVD_R support CDC_DVD support CDC_CD_RW support CDC_CD_R support got disc status: 0 I can give an ssh login for debug, just say me when -- hal detects written DVD as empty https://launchpad.net/bugs/14692 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
