[ale] Questions about DVD-R

[Dow Hurst]

Pizza,
What part of the below output is the part that tells about DAO versus 
TAO?  This is a LaCie external Firewire DVD that is supposed to write 
-R/-RW/RAM.  I haven't been able to use TAO mode.  The attempt fails 
with an error that I don't have at the moment to put here.  Thanks,
Dow
