[mythtv-users] 0.17 Recordings Keep Switching to Tuner 0

[John Kondis]

MythTV keeps changing the input source to the tuner
(Tuner 0) every time a scheduled recording starts. 
The backend is set up to take input from the S-Video
input.  I've triple-checked that mythtv/setup has the
card set to S-video, but the problem persists.

When I reboot and go to live TV everything is fine; it
shows the video from the S-Video input.  Whenever a
scheduled recording starts, it switches to tuner 0 and
I get nothing but snow for my recordings.  Now, when I
go back to live TV (say, after killing the recording
or letting it finish), it remains on Tuner 0 (snow)
until I reboot again.

How do I fix this?  This is very annoying as now I've
been missing all my scheduled recordings and have to
reboot frequently.  Any help is appreciated, though no
one ever seems to have an answer to my questions on
this mailing list.

Note that I recently changed from using the tuner
input to using S-video because the quality is better
if I avoid the mod/demod to channel 3.
