[CentOS] cdrecord issues

I have an issue with cdrecord though and I can't figure it out. I use
Webmin, which basically just creates an iso and then uses cdrecord to
burn it and it worked fine with previously installed CentOS 4 (I wiped
and reinstalled about 8 months ago).

This is the command that Webmin tries to execute...

cdrecord -v dev=0,0,0 speed=4 -isosize \
'/home/Linux/CentOS-4/CentOS-4.2-i386-bin4of4.iso'

The result of cdrecord -scanbus at bottom of email. Log of error just
below.

Help appreciated...
