Well, that happens me too! i have a 24x LG cd-rw and when i'm burning or
reading cds i can't do anything else! My hw is a bit different (that's
my office pc, I'D NEVER BUY iNTEL) hp vectra vl420 with p4 1.6GHz and
800MB SDRAM, so i suppose it dowsn't much depend on that...

I have the same problem, I also use a 24x lite-on cd burner.
It worked fine with 8.2, but using 9.0 (kernel 2.4.19-16mdk) it seems to
take an age,
30minutes for a 20mb cd :-(
I have noticed that during burn the red light of the cd only comes of
for short pulses
then it goes green, so it's not writing very often. When I first used it
I aborted it after
a while as I didn't think it was working only to see that it had burned
some of the cd,
but VERY VERY slowly.
I'm using an XP1500 with an ASUS A7V133 m/b with a clean install of 9.0 !
It's nice to see it's not just me :-(
