Just to put an update out there I finally am able to get firewire to work
fairly reliably. Thanks for all the help. I ended up having restart the
cable box and then running

plugctl -n 0 oPCR[0].n_p2p_connections=0
 plugctl -n 0 oPCR[0].n_p2p_connections=1

To get the port to start working if it ever stopped but it really only hangs
when I am playing with the settings. Also one strange note I hade to turn
off p2p connections then turn it on to work. I'll add this to the end of my
mythbackend script and it should fix me up. Again thanks for all the help.
