No, it's run entirely on-demand by irexec. There's an entry in the
.lircrc file that binds it to a remote button. The advantage of doing
it this way is that the second instance of X need not run until
someone actually goes to use the second TV.

The script runs as whatever user irexec runs as, which should be root
in this case. That way, the script can start X as either user and no
password is needed. Personally, I have my system start at runlevel 3
(instead of 5), so that I never see a gdm/xdm login prompt. I just
press the special button on my remote and X starts up, followed by
Myth. You can set the runlevel by editing /etc/inittab.
Here's the .lircrc entry for the "downstairs" TV, which uses the
prog = irexec
button = Go
config = switch-video
and for the "upstairs" TV, which uses a generic RC-5 remote:
prog = irexec
button = vcr1-standby
config = switch-video tv2
where "switch-video" is the name of the script I posted previously,
stored in /usr/local/bin.

I actually find that, for the 350, the "use the built-in decoder"
function is not necessary with recent versions of IVTV. Its
framebuffer is quite capable of keeping up, and I always found using
the decoder to be somewhat unstable. But, if you do want to use it,
then you do have to figure out which DB setting to toggle, yes.
