I don't think the distribution is important here. While I'm not familiar 
with Mythbuntu, I would be surprised if the networking is different from 
Ubuntu. As both setups are identical (except the IP address), I would 
assume the reason for your problem can't be seen easily from the 
configuration.

Possibly you have done this already but I would first check if the non-
working machine uses the wrong interface (if there is a second network 
card), i.e. maybe it should be eth1 instead of eth0. And then I would 
check if the cable is working. Usually there are lights on the switch 
indicating if there is something connected to the individual ports. You 
could unplug the cable from the machine and the light should go out and 
it should go on again when you reconnect the plug.
