Yes, the F/E is accessing the database over the network, but I guess my
point is it doesn't seem like it would be a bandwidth issue because I can't
imagine just accessing the database is stressing the network. Unless the
HDHR is taking up almost the entire bandwidth, which seems unlikely, and any
little extra activity is pushing it over the edge. Even if this was the
case I would expect to see some evidence of dropped packets, or something

It was a new master B/E, but no I didn't duplicate the setup on different
hardware, and really can't because at least at this point I'm not about to
pull the two working tuner cards out of my B/E. Like you said, it was
pretty much a shot in the dark. All I did was prove that the HDHR could
work with Myth in a split B/E, F/E setup, but I guess I pretty much already

I have not looked into the power supply, but I guess I should add it to the
list of possible issues. The thing is if it was a P/S issue I would think
that other types of extra activity on the B/E should be able to cause the
same problem, but as of yet I have not seen that. Unless the Myth F/E is a
lot more of a resource hog that I think it is.
Have you tries removing IPCop from the equation for a test?
Other than moving the B/E and the HDHR out of the DMZ and into the internal
network, which now seems like it should be on my list of things to try, I'm
not sure how I would remove IPCop from the equation.

You're right, I'm probably trying too many things at once, but some of that
is due to lack of time and/or resources. My frustration is coming from the
fact that other than a slightly atypical network setup, I don't think I'm
trying anything crazy here. This thing should "just work", or if it doesn't
work should be kicking out some type of error, whether it be in netstat,
ifconfig, dmesg, /var/log/messages, etc. and I'm just not seeing that.
Thanks again for everyone's input; it is very much appreciated.
