So near, and yet so far!

I removed the other 2 tuners, just had the single 292e plugged in, and 
rebooted.

Set the new card up, ran a channel scan, and it found some channels!

However, when I tried the frontend, I couldn't look at any of them. 
System just went straight back to the menu as soon as I pressed on 
"Watch TV".

I went back into the setup and looked at the channels that were found. 
There were only 2 transports that had been found (the SD tuners find 
about 5) and neither of them had BBC1 HD (which feels like a good 
starting point).

I edited one of the transports to 770MHz, and deleted the other 
transport, then did a scan just on that transport. This found nothing. :-(

Since then, I've just done a new full scan. I'll look at the output of 
"sudo service mythtv-backend status".

Just finished the scan. It's only found 2 transports again. 698Mhz ans 
738Mhz. These are both SD frequencies 
(https://ukfree.tv/transmitters/tv/Mendip).

Running "sudo service mythtv-backend status" all looks fine.

When I run the frontend and try to watch live TV (I set the start 
channel to 3, which is did find), it just comes straight back to the 
menu again.

Running "sudo service mythtv-backend status" again brings up ...

Any ideas why it's not finding many channels, or why it's not displaying 
the ones that it does find?

I've got the replacement signal booster and splitter arriving today, so 
I can try again when that's in play. However, when the 292e was plugged 
into my Windows machine, it found (and played) all of the right channels 
without going through any signal booster.

I haven't done the step of making sure that tuner identities remain 
consistent between reboots yet. I'm keeping things simple and having the 
292e as the only tuner in the system for now.

Cheers,
Damian
