Comment (by leafpaulc@…):
Sorry this is long winded but the behaviour is odd. I think that the
mythbackend running is a red herring (partially at least or possibly a
second issue), in that it gets rid of the card not recognised error in
backend setup (once killed) but doesn't solve the underlying problem of
the card not working with mythtv 0.28.
I don't think that the back end is running (initially - see output below),
this is a clean install and on boot the mythbackend set up runs
automatically. If I exit it prompts "Do I want to start the back end".
I still have the problem that the tuner doesn't work in the front end.
From the output below it would appear that if the back end is running,
then running mythbackend setup does not cause the backend to shutdown
(which it should shouldn't it?).
See below for ps output.
This output is after the backend set up has started (still get the error
with this but no backend running, just the backend set up):
sudo ps -ef | grep myth

paul 5500 2179 0 16:26 pts/1 00:00:00 grep --color=auto myth
At this point I still get the card not recognised message.
When I exit back end set up and am prompted "Do I want to start the
backend" - "Yes" I get:
sudo ps -ef | grep myth
paul 1454 1366 0 16:06 ? 00:00:00 /usr/bin/ssh-agent

--quiet --syslog local7
paul 5650 2179 0 16:31 pts/1 00:00:00 grep --color=auto myth
Now if I try mythbackend set up again, mythbackend is running (as well as
set up) - NB shouldn't I have received a prompt at the launch of
mythbackend setup stating that mythbackend will be stopped? - I didn't get
one:
sudo ps -ef | grep myth

Now the card is recognised (as you suggested) but when I try to add the
second tuner on the same card (it is now also recognised), on the LNB*
config screen it has "Unconnected" but doesn't open up the overlay to
choose LNB and configure it when "Unconnected" is clicked. Nothing at all
happens when "Unconnected" is clicked.
if I try to scan for channels on the second tuner I get "Failed to find
any new channels!" possibly because the LNB part cannot be set up. Now
that the first card is recognised I can scan for channels using it, they
are listed but when exiting and running mythfrontend to view the tv I
still get the 10 seconds of "Please Wait" then nothing (back to the front
end tv etc menu).
Weirdly - on the fresh install ie just after the first installation I was
able to set up the first tuner, including LNB and scanning channels
apparently successfully but I cannot see live tv.
