 Often I fail to get live video or a successful recording using mythtv.
 However, when I start kaffeine afterwards and tune to that channel, I get
 video without problems. Subsequently starting mythtv again allows me to
 play that channel, as well as switch to different channels, so I assume
 mythtv does not correctly initialize my tuner.

 I run mythbuntu 14.04.1 and have a DVBSky S950C PCIe, using the latest
 firmware and 140619 driver provided by DVBSky. I have a XBMC Windows
 frontend, although for the failed recording this should be irrelevant.

 dmesg | grep dvb

 [ 11.000016] cx23885_dvb_register() allocating 1 frontend(s)
 [ 11.000019] cx23885[0]: cx23885 based dvb card
 [ 11.296398] m88ds3103_load_firmware: Waiting for firmware upload
 (dvb-fe-ds3103.fw)...
 [ 12.532031] Registered IR keymap rc-dvbsky
 [ 20.009008] dvb_ca adapter 0: DVB CAM detected and initialised
 successfully

 There are some errors being reported in dmesg ( like [128.828029]
 cx23885_wakeup: 17 buffers handled (should be 1) ) but they are probably
 red herrings since they also occur after a cold boot and and successful
 video playback.

 I have tried turning off EIT collection. This reduces the frequency of the
 problem, but does not eliminate it.

 The attached log file (-v channel, dvbcam, eit) seems to indicate that
 tuning is successful, but still a videostream cannot be started.
