There was a dicussion regarding this issue on the cdwrite list and as I 
recall, it is possible for the auto mounting processes to screw up a burn.

I have burned coasters when burning at a speed higher than the media was 
identified.  I think that cdrecord has been modified such that it won't 
burn at a higher rate than the media is though.

That brings up an interesting point.  I've not thought about it 
affecting music playback.  I generally don't use the automount/autorun 
processes anyway.  I prefer the old CLI mount command...

I've not got any experience with dvd yet.  With cd-r I've had good luck 
with just about everything.  TDK, Iomega, Verbatim, even some nonamed 
disks that had no labels on the case or the disks themselves.  I can't 
recall the last time I burned a cd coaster.

This is pretty interesting.  I've still not installed my dvd burner into 
the box I intend it to stay in.  Once I do, we might start doing some 
comparison burns.
