OK.  How do I make sure any firewall is off? 
sudo iptables --list

Chain INPUT (policy ACCEPT)
target     prot opt source               destination        

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination        

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination   

Isn't that off?  Notice that there is no reference to either eth0 or eth1...


Could be that the switch is not working.  I will bypass it and only 
connect one of the tuners.

I did remove power to one of the hdhr's for a minute and still did not 
see any activity on tcpdump.
