[TriLUG] cdrecord & cpu usage

[zzd]

When burning ISO images to cdrom, I find that I am totally unable to do 
anything else during the burn process, including move the mouse or 
change to alternate windows. I like to use Eclipt which is a good GUI 
front end to cdrecord, and when I use the top command, it shows 
cdrecord at over 40% cpu.

So, how do I (re)nice the cdrecord command to use less CPU, so that I am 
at least able to read/write emails while at the same time, burning a 
CDROM? I tried "nice --adjustment=10", but this did me no good. The 
whole nice thing is a bit confusing. Any help/direction appreciated.
