The above is likely your problem.  Setting n_2p_connections=1 tells the 
STB it should be sending data on whatever channel is already set.  Mythtv 
setups up its own plug, and with the patch I sent you picks its own 
channel.  Since you already have the STB sending data over a 
different channel prior to starting mythbackend, its likely the STB 
ignores our request to send data on the channel the backend wants.  

Idealy you should not need to use any plugctl hack, nor should anyone.  If 
you must, try setting the channel=0, and also put that line above 
n_2p_connections=1

#! /bin/sh
plugctl -n 0 oPCR[0].n_2p_connections=0 
sleep 4
plugctl -n 0 oPCR[0].channel=0
sleep 4
plugctl -n 0 oPCR[0].n_2p_connections=1
sleep 4
plugctl -n 0 oPCR[0].bcast_connection=0

instructions on compiling are at the top of firewire_tester.c.

You will want to run 'firewire_tester -p -n 0 -r 5' this will test 5 p2p 
connections on node 0.

sorry I meant -v channel,record
