Thanks Andrew and Jeremy.  I apologize for not experimenting a bit
further before posting that query.  In the meantime I discovered the
"Verify and Boot" option (which gave me a FAIL)

I also checked the directory that the bittorrent download created and
found the attached SHA1SUM which confirmed that the ISO image on my
harddrive is fine.

[ush at localhost ~]$ cd Fedora-9-Beta-Live-i686/
[ush at localhost Fedora-9-Beta-Live-i686]$ sha1sum -c SHA1SUM
Fedora-9-Beta-Live-i686.iso: OK


So I guess my burn process is corrupted.

Thanks for the help and apologies for not checking those out first.
I've become used to seeing SHA1SUMs on websites offering downloads so
it threw me a bit when it wasn't there.

OK, on with the testing.
