For whatever reason, I stop then start the backend which kills the firewire connection. I already have it setup in mythtv-setup so I don't have to do anything with that. So I disconnect the firewire cable from the back of my cable box for about 15 seconds plug it back in and then do a soft power down and then power back up using the remote on the cablebox. I then set the channel on the cable box to a known good channel using my remote (I don't think you have to do this step but I do it b/c it works). I then run a script I wrote called mythfwreset that basically does the following
<br><pre>plugctl -n 1 oPCR[0].n_p2p_connections=0<br>plugctl -n 1 oPCR[0].n_p2p_connections=1<br>plugctl -n 1 oPCR[0].channel=63<br>plugctl -n 1 oPCR[0].bcast_connection=0<br></pre>This basically shuts down the firewire p2p connection, restablishes and turns off broadcast. I usually then run test-mpeg2 to make sure it is working and then if everything is good start the frontend back up. Every once in a while I have to do this a second time because it didn't work the first time but only about 10% of the time and I never have to do it more than twice.
<br><br>Because I have to power down the cable box I haven't taken the time to script all of this but I would guess that using either a good universal remote or someone good with the firewire interface could power off the cable box letting you script everything but I just haven't done it yet. Give this a shot and if it doesn't work for you post the plugreport output from after powering down and up the cable box but before the plugctl commands and then after you run the plugctl commands and we can go from there. Hope this helps and if I am confused with what you are getting stuck on point me in the right direction.
