[G4] Burning DVD glitch

[Rick Barrett]

I put a DVR-111D in my B&W (now G4/1MHz), when I try to burn a DVD  
Toast 6 won't do it, says something like "this operation unsupported".
System profiler reads:

PIONEER DVD-RW  DVR-111D:

   Burn Support:	Yes (Unsupported)
   Profile Path:	None

   Write Strategies:	CD-TAO, CD-SAO, CD-Raw, DVD-DAO

What am I missing?
