<br>is your stb jumping nodes on you? some moto boxes in particular will initialize on node 1, but jump to node 0 on bus reset. it looks like that is what is happening to you, which could confuse things.<br><br>the best way to check it is on a fresh boot. first, stop the mythtv backend server, as it monitors firewire and gets in the way of testing. next, check the node the stb is on with plugreport, then reset the firewire bus:<br>
<br>$ firewire_tester -R<br><br>and check the node with plugreport again to see if it has jumped to node 0. then, try priming the firewire connection. once it is primed, i suggest setting the starting channel for the firewire tuner in backend setup setup step 4. to the *same* channel you just primed with, as it is a known clear channel. then restart the backend server, try watching livetv and see how things go.<br>
<br>you might look into mythprime- a firewire primer based on firewire_tester. a link to the current beta version with instructions is here:<br><br><a href="https://help.ubuntu.com/community/MythTV_Firewire#head-354bd119b272d0ad32bcd2454a042b16100b86b0">https://help.ubuntu.com/community/MythTV_Firewire#head-354bd119b272d0ad32bcd2454a042b16100b86b0</a><br>
<br>a final, more robust version, including a channel changing option to prime on a known good channel, should be available this weekend along with a new beta version of the firewire channel scanner.<br><br><br>good luck!<br>

<br>> I put in another card, and same problem:<br>

After this, the connection is dead until I manually reset it:<br>>
myth:~# firewire_tester -P 1 -b -n 1 -r 1<br>>
Action: Test broadcast 1 times, node 1, channel 62<br>>

Seeing that the DCH-3200 is an explicit choice of firewire STB in<br>>
mythtv-setup, it has to work for some.<br>>
Any idea what's going on then?<br>
