[mythtv-users] Ceton Infinitv ETH 6 configuration

[Ronald Frazier]

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.

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:
get_var.json?i=1&s=mux&v=ProgramNumber


Note, the i parameter will depend on which tuner you are using. If you
investigate that request, do you see the response having been:
{ "result": "280" }

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.
