If I was guessing I would suspect that the network was not fully up when it 
looks for the HDHR.

What runlevel is dhcp, and what runlevel does mythtv startup as, and is the 
network fully up when mythtv tries to start?  You may want to put some simple 
debugging code in the mythtv startup script to save the network status at the 
time the script runs (something like "ifconfig -a > /tmp/somefile"

And even if the runlevel for dhcp is before mythtv, it still may not be fully 
configured by the time mythtv tries to start, if the mythtv runlevel is higher, 
and the network is still not quite there yet, you may have to put something in 
mythtv to delay the startup a set amount, or delay until you have an ip address 
(and fall out after a fixed amount of time that would indicate other issues).
