With the All Blacks playing this weekend I've been pushed to get MythTV
working so we can watch the game on Prime (We don't have a TV).
Problem:
Start MythTV front end, select watch TV, choose Prime (doesn't matter
which channel I tried) after about 5-7minutes screen goes blank, sound
stops. If I try to change channel at this point (e.g. to TV1), a still
image of what was last on current channel (e.g. Prime) comes up with the
OSD "channel info" displayed along the bottom of screen, doesn't change
channel and no video/sound on current channel. I have to use keyboard
"esc" key to go back to main menu and click on "Watch TV" again. Note
I've check screen saver is off:-)
Doesn't appear to matter which channel I choose although, oddly as soon
as the "Infomercials" came on TV1 at 8:30am (after crashing 3 times from
8am) it was fine for over an hour. I've never sat through and hour of
infomercials before and now can't wait for my new robot vacuum cleaner,
hair condition and ab roller to turn up!:-(. Changing away to TV2,
liveTV crashed again but then worked fine on C4 for 50 minutes before I
changed to Prime which then crashed.
Signal 45% with SNR 4.8d/b, local transmitter is only 3km away direct
line of site with roof antenna.
Only thing I can see in backend logs that means anything is "Changing
from WatchingLiveTV to None" but I can't see why it changed. e.g.

Setup:
MythBuntu 12.04.4
MythTV 2.7 with fixes (Frontend and backend on same computer).
Motherboard: Asus P5WDG2 WS Pro, Intel E7200 2.53GHZ, 3GB RAM.
Video: Galaxy NVIDIA GeForce GT 430 (43GGS8HX3SPZ) 1 GB DDR3 SDRAM PCI
Express x16.
Tuner: WinTV-HVR-1100 Hauppauge PCI DVB-T Digital TV Tuner Card.
I also have Zoneminder working on this computer with two analogue
cameras. "top" with LiveTV working CPU usage doesn't go over 30% with or
without Zoneminder running, with just Zoneminder CPU is about 10% or
less. I don't think Zoneminder is the problem, I've just watched an hour
of Prime this evening without an issue and I've started and stopped
Zoneminder over this time.
OK, looks like it is an intermittent problem since LiveTV has worked
perfectly this evening for the last 90 minutes on Prime. At least Top
Gear was worth spending the time on.
What I should be looking at to figure out why LiveTV ramdomly stops working?
Thanks
Steve
