  I'll respond to both of you at once, Robin is correct, this was logged
just after LiveTV failed, I've seen error messages channel changes
during recordings:


Sep  2 22:00:02 front-main mythbackend[1902]: E TVRecEvent
v4lchannel.cpp:786 (SwitchToInput) V4LChannel(/dev/video0):
SetInputAndFormat() failed
Sep  2 22:00:02 front-main mythbackend[1902]: E TVRecEvent
tv_rec.cpp:3681 (TuningFrequency) TVRec(2): Failed to set channel to 8.
Reverting to kState_None
Sep  2 22:00:02 front-main mythbackend[1902]: I TVRecEvent
tv_rec.cpp:1029 (HandleStateChange) TVRec(2): Changing from
RecordingOnly to None
Sep  2 22:00:02 front-main mythbackend[1902]: I CoreContext
scheduler.cpp:637 (UpdateRecStatus) Updating status for Castle:"The Fast
and the Furriest" on cardid 2 (Will Record => Recorder Failed)

So now I'm wondering if the driver isn't actually handling the analog
side of the card.  I've had this card actually record only once and that
was with a misconfigured IVTV driver for the kernel.  I dropped that
driver because it's not the correct one for the card, and for some
reason 12.04LTS doesn't properly recognize my PVR-150, which prompted
the purchase of the HVR-1800.
