I've been trying to trouble shoot this issue for 2 days now. I feel like I've read every forum, watched every video and no solutions are availing themselves.
I've authored a DL disk in DVDSP.
It has 2 video layers that share the same audio track.
Each video layer is approx 100 minutes.
I've exported both video files from FCP, multiple times to make sure the GOP structure matches.
Other items on the disk are simple a small slideshow, and some simple menus.
I've been able to successfully follow instruction to set my own breakpoints and have been able to build and format the production to hard drive. But when I try to burn it using Toast to disk it fails and says: MEDIUM ERROR Sense Code = 0x73, 0x03
When I try to build it in DVDSP I get: Unknown device error (0x09, 0x01) - to which it was suggest that I try different media, I have... same problem exists.
It has been suggested that maybe my burner is dead - yet I can still burn DVD-5 just fine.
Any advice you can give would be key. This isn't the first time I've built a DL DVD in this program, but it's the first time I've ever had these issues.
