first setup an HDHR on my network and Myth backend.  I was banging my head
against the wall trying to solve the problem because there were no obvious
error messages or anything like that on either the backend or the frontend.
I finally traced the problem to the fact that the on-board network interface
on the backend MOBO simply couldn't handle the traffic of recording the HDHR
stream over the network and streaming to the frontend.  I threw an old 3Com
10/100 NIC into a PCI slot and the problem went away.  Not really happy
about having to give up the slot, which I could have potentially used for
another tuner card, but I had to do it.  I eventually upgraded to GB NICs
and a GB switch, but that really wasn't necessary.  Like I said, could be a
totally different situation for you, but I thought I'd pass on my experience
to potentially save you some headaches.
