The command that you used above will not work.  For starters, unless 
you're using a SCSI CD burner, your CD burning device is not /dev/scd0. 
Some truly ancient distos (like Caldera, or Debian stable) treated all CD 
burners as SCSI devices, but FC1 was most definitely not one of them.  All 
that you should need to run to burn an ISO with cdrecord is:
cdrecord -v ~/Downloads/Fedora/FC-6-i386-disc1.iso

However, before creating any more coasters, have you verified that your 
ISOs are even valid?  This entire problem could be due to bad ISO images. 
The best place to start would be checking their md5sums.

I really doubt it.

Yes, several times, and never had a single problem.
