So I left it for a while The other day it started to play up again. Since I have some time I invested more time in debugging the problem. This is what I'm seeing in the debug log. I had to modify rsyslog's config to get this. This is interspersed with the output from tzap: [root@mythtv ~]# tzap -c channels.conf -a 2 -f 0 -d 0 "Ten HD" using '/dev/dvb/adapter2/frontend0' and '/dev/dvb/adapter2/demux0' Sep 25 12:20:58 mythtv kernel: power control: 1 Sep 25 12:20:58 mythtv kernel: tda1004x: setting up plls for 48MHz sampling clock tuning to 585625000 Hz video pid 0x00a1, audio pid 0x0051 Sep 25 12:21:00 mythtv kernel: tda1004x: found firmware revision 29 -- ok Sep 25 12:21:00 mythtv kernel: tda827x: tda827x_init: Sep 25 12:21:00 mythtv kernel: tda827x: tda827xa_set_params: Sep 25 12:21:00 mythtv kernel: tda827x: tda827x_config not defined, cannot set LNA gain!

Tda827x doesn't seem to have any configuration options. Suggestions? Remember this system did work previously.
