Can anybody explain this weird behaviour (tvheadend 3.3.511~g1f4f001 on OpenELEC 3.0, on an Arctic MC001)?
Until yesterday, I had all 6 MUXes from the nearest transmitter (Midhurst) available on all tuners, all working beautifully.
My setup uses the built-in DVB-T tuner of the Arctic, plus 2 dual DVB-T USB sticks, and a DVB-T2 USB stick.
After a reboot, I had duplicated devices, so I deleted the contents of the folders dvbadapters, dvbmuxes and dvbtransports, then restarted the tvheadend service. (I've done this before, and not had a problem.)
After the restart, tvheadend failed to detect any services on any of the 6 local muxes, but was able to pick up a few muxes from more distant transmitters, with lower quality. As a result, all I can get is the BBC services on PSB1 - other MUXes are either not working or have very high error rates, with drop-outs/pixellation.
My first thought was that my aerial had been damaged, or maybe Midhurst was down or that 4G transmissions had started causing interference, so I transferred the USB-connected DVB-T2 tuner to my other PC (which runs Ubuntu 12.04 and tvheadend 3.5.23~g4724e01). I hooked this PC up to the same aerial downlead, and was immediately able to scan all the local MUXes, including the HD ones.
So the problem must be related to the setup on the Arctic... or maybe, when I purged the duplicate DVB devices, I inadvertently stuffed something else in the tvheadend configuration...??
Any ideas gratefully received...
