Tvheadend

So yes, using the "unstable" branch, and got hit by the [[https://tvheadend.org/boards/5/topics/9792]] DVB-rewrite merge last week.

Everything's back up and working, but I'm having one niggling problem with one mux:

In the UK, the mux carrying BBC One HD and BBC Two HD wasn't automatically discovered on the first scan. I had to enter it manually, and I had some problems with that (some were me, initially using the old details, but also some odd UI behaviour - btw it would be great if you could explicitly tell it to re-scan a mux after editing its details. It does it if you create a new one, but not if you edit an existing one). And there were some problems scanning that mux; it didn't seem to want to find the correct transport stream id (2050) and on some scans seemed to pick up the wrong set of channels because of that, but I was unable to enter the correct value. But eventually I got it in...

For reference, that mux is (included because there clearly are some issues with initial/auto scan and this mux):

Delivery system: DVBS2
Frequency (KHz): 10847000
Symbol Rate (Sym/s): 23000000
Polarisation: V
Modulation: 8PSK
FEC: 2/3
Rolloff: 25 (read from pre-dvb-rewrite config, possibly helped to get it working at all)
Transport Stream ID (read-only): 2050

But I kept having problems getting it to switch to it properly (from XBMC), getting a "No free adapter" error. And this logged in tvheadend:

2013-11-21 13:43:21.842 subscription: No transponder available for subscription "192.168.1.149 [ rachel | XBMC Media Center ]" to channel "BBC Two HD" 

Eventually I got it working - I knew there wasn't a hardware problem as I'd been viewing those channels a lot using the same hardware before the software upgrade. And I think the way I got it working was basically by getting everything mapped properly.

ie: In the Configuration->DVB Inputs->Services tab, making sure the Service "BBC One HD" and "BBC Two HD" are mapped to their channels.

So I did all that, and it works.

But every time I restart tvheadend, that mapping is lost again, and I get the same "No transponder available" error, until I go to the web ui and set up the service->channel map again for those two channels.

ie: that mapping, that I had to set up manually, does not persist between reboots.

So there are some problems with autodetecting it and setting it up automatically in the first place, where nearly everything else (and every other channel I care about at least) just worked. But having got it all in manually, it keeps losing that mapping from service to channel, on restart.

(BTW this is a Hauppage WinTV Nova S2, which is the subject of some other threads at the moment, I see; I've been using the standard firmware in ubuntu linux-firmware-nonfree throughout.)
