cd burner partly working

[Jude DaShiell]

On redhat 8.0, I have an HL-DT-ST cd burner running.  It reads disks with 
no problem.  If I make an iso image with text files in it and directory 
structure and try to burn it to a cd, the burn is good.  Afterwards I can 
read what I've burnt.  Unfortunately, on that same system with that same 
CD burner with the same setup, it will not burn a good copy of fedora core 
2 install disks.  Later this weekend, I'll try mounting those iso's from 
the hard drive and try the install on the hard drive.  Those iso's were 
downloaded with rsync so I'm pretty confident I at least have good isos. 
The burner may only be marginal so I have a replacement burner sony 52 50 
which may work better.
