[Bug 46410] Re: Nautilus should warn before burning a CD without DMA-support

[Jan Claeys]

Everytime 'burnproof' or another similar technique has to kick in, it
adds a small gap into the burned data-stream, which might cause error-
correction slow-downs when reading the CD back in, and occasionally
causes the disc to be unuseable (despite there having been no
'uncorrectible write-errors' reported).

I think the situation is worst when both CD-writer & hard disk have no
DMA though.  This happened on my dad's laptop with hoary because the
chip responsible for IDE was not recognized (it was 1 of the first
Turions on the market).  This resulted in 20, 30, or more 'burnproof'
interventions when trying to burn a CD using the default settings, and I
had to burn CDs at single or double speed to get anything useable.
(Breezy development added the chipset and solved the problem.)

So, maybe a suggestion to set a lower writing speed could be added?

(Also: what with older cd-writers that don't have buffer underrun
protection?)
