Rescan, now can't play LiveTV

*Mumble* Stooopid HGTV and Bravo channels....grumble...."making" me do
a full re-scan...*moan*....now liveTV ("Watch TV") isn't working...

As above, with this month's new FreeviewHD channels Bravo and HGTV
(until they fold / are replaced by even crappier channels next month)
I foolishly did a full rescan and now liveTV doesn't work i.e.
selecting 'Watch TV' results in nothing, with a terminal error that
LiveTV window couldn't be opened.

I haven't touched or altered any storage directory locations or permissions.

It's always confused me how after a scan there are multiple versions
of the same channels, which conflict, and multiple unassigned
channels.

Have tried deleting the input source ("FreeviewHD") and starting
afresh in mythtv-setup, but although the channels are found on a
rescan, and have the correct names and channel numbers and service
ID's, still no live TV.

Am in Palmerston North, using WhÄrite transmitter, if that's helpful info.

Sorry, as a followup to my own message, I have just realised that I
can record programmes & watch them back as recordings, so the tuner(s)
(HVR-2200) are locked in OK, and the EPG (via tv_grab_nz-py) is
functioning. Arch Linux box, by the way.

Hmmmm....

[SOLVED]

Turns out my httpd.service had failed (thanks to me accidentally
deleting the folder '/var/log/httpd' for another reason).

I noticed my mythbackend.service file needed httpd.service before it
would start. Odd that it started nonetheless with no apparent errors
except silently failing to play LiveTV.

Oh well, all is back working as expected.

Weird, so it refuses to start if it can't write logs?
There should be *some* log of the error somewhere, surely?

Actually, I'm not sure what's going on with it. I can watch LiveTV on
a remote frontend, and everything works on the FE/BE combined machine
*except* LiveTV. Have fiddled with directory permissions, tried
starting mythbackend as different users, and adjusted nvidia drivers -
all to no avail.

When I get some spare time I'll try to dig through the logs. If I ever
get it diagnosed and fixed I'll report back!
