I've used burncd for some time with a standard CD writer and I
*thought* I tried the same thing, some time ago, using "fixate"
on the DVD drive without success. Perhaps I was mistaken or maybe
the version of burncd was not late enough.

I have 5.21 and found most of the above in the source code so it
looks as though I can write double layer +R but will need to
upgrade to write double layer -R.
WRT -use-the-force-luke=break:size, is this a necessary option or
will it default to a sensible value?
