Media Check errors on Fedora Core 6

[Thompson Freeman]

Another of my silly little "challenges". As in things  
aren't quite working as expected 8-/.

I have downloaded the cd isos for FC-6, and the sha1sums of  
the images test as good. I have burned to cd two complete  
sets of cds, and gotten one cd to pass the media check  
step. _Everything_ else fails, and fails multiple times.
I have looked at bugzilla and not found mention of this  
being a problem as it has in the past with fedora.

Is anyone else having similar challenges, or should I  
assume the problem is entirely on this end?

As a side issue, how would I get the sha1sum of the burned  
cd? I believe that should remain the same as the image  
file, or am I completely a sea?

Thanks in advance for your help
