Dag yum repositories broken?

[Jason Costomiris]

Every time I do a yum check-update, I get problems with Dag's 
repositories.  I've used several different Dag mirrors, all with the 
same troubles.

First, there were problems with corrupt header.info files.  Now there 
are problems with various headers (first libebml-devel, now 
libmatroska-devel).

I've gone so far as to do a yum clean all, and try again, but the same 
results are had..

I've now gone even a step further and renamed /var/cache/yum, recreated 
the directory and started a new yum check-update.  It downloads a bunch 
of headers, but pukes and dies on the same packages as before.

Any thoughts?  I've emailed Dag, but with no response.
