[LUNI] IDE CD burner frustrations

[Steve Johnson]

It could be the speed, but I doubt it, usually selecting the wrong speed
only results in a useless cd, but you never know!  Also, I'd make sure
that your burner is not on the same ide bus as your root drive.  And
make sure you have your iso, or whatever files your burning from on the
seperate bus, ie: primary ide for root /dev/hda? and your burner on
secondary ide bus.  Sometimes what can happen when sending file to
burner form same bus is it will underun.  Data will get bunched up while
app reads from same bus it's trying to write to, if that makes any sense
:)
The other thing is make sure your burning directly to the /dev/scd0
device and not your mount point for the device, ie. /mnt/burner, as that
wouldn't be mounted since you can't mount a blank cd.
