Thanks for the ideas Franklin.
This looks like it might open a can of worms ...

First Etch:
hal-find-by-capability finds the DVD-RW drive but does not find the
Plextor CD-RW drive (yet Etch works the CD-RW OK!).

Second Lenny:
hal-find-by-capability finds the Plextor CD-RW, but not the DVD-RW!
With no blank media in the CD-RW, it reports 
 " storage.removable.media_available = false  (bool)"
With blank media present, it reports
 " storage.removable.media_available = true  (bool)"

Exactly what we would hope for I think. But GNOME seems not to recognise
this. 
I have just written a CD image under Lenny using wodim. What now?
