<div dir="ltr">Nope, that's not what's going on. With a cablecard, you still need to know the program number so you can appropriately handle the mpeg packet stream. So myth tells the ceton to tune in the channel, and then checks (multiple times) for a non-zero program number to show up in one of the status fields. If you are not getting a program number, then my suspicion is that they changed the way something works in the web interface.<div>
<br></div><div>Do you have google chrome installed in your machine (or firefox with firebug)? If so, browse to the ceton web interface and go to the tuner page where you can set the channel. Press Ctrl+Shift+I and go the the Network tab (or open firebug and go to the Net tab). Use the "Set Channel" box/button on the page to change the channel, then watch in the debug (or firebug) console below. Do you see a request for the following:</div>
<div>get_var.json?i=1&s=mux&v=ProgramNumber<br></div><div><br></div><div><br></div><div>Note, the i parameter will depend on which tuner you are using. If you investigate that request, do you see the response having been:</div>
<div>{ "result": "280" }<br></div><div><br></div><div>If you do see exactly this (though the actual program number will be different), then I'm not sure what the problem is offhand. If you don't see it, then look around in the debug/firebug window and try to determine what the request/response was to get the program number.</div>

</div></div>Probably not going to be much help since I don't have one of these...<br>
but typically with ATSC and QAM tuners, you specify a channel and a<br>
'program'. The program number is the multiplex to tune. If your<br>
using a cable card, you won't specify a program since it will use a<br>
channel map to map channel 10 to channel 123 program 5 (for example).<br>
<br>
That non-zero program number error makes me think that perhaps MythTV<br>
is sending the physical channel and program, rather than the logical<br>
channel number that the card expects.<br>
<br>
Perhaps somewhere in the setup you set it to QAM when it shouldn't be?<br>
