I've been using cdrecord to burn audio (or data) to cd-r's for
a number of years, but -- here, in 7.10 -- I tried burning first
with Serpentine, then with Rhythmbox (I assume each uses the same
app). In each case, they failed with a pop-up box wanting a
cd-rw disk.
Any way to set these to work with cd-r's?
