btaudio is for analog tuner cards. Pretty much the only thing it can be with
a pvr-250 is that you've not setup the output sound device in mythtv's
settings section or something else is using the dsp device and preventing
mythtv from opening it.

Sounds like you're not running a window manager on there, or are running one
that doesn't work properly wrt keyboard focus.

Hrm... okay, I'm GLAD to know that it's not btaudio.
I have three sound devices in /dev:
/dev/dsp /dev/dsp1 and /dev/dsp56k

In mythtv's setup for my 'Capture Card' settings, I have:
Audio Device: /dev/dsp

I just changed it to /dev/dsp1 and it works now!
I have sound. It's very quiet, but I can just adjust my volume.

Quality of picture is pretty bad though (It's at 480x480)
I'll have to look at improving that...
So the sound problem is fixed.

I'm running fluxbox. I believe the same thing happened though with stock
KDE.
I'm running the programs/script using Eterm.
Is there some way I can 'turn off' the keyboard for screen 2?
That way only the remote control will be sending keys to that scree
I just tried running mythforeground and irxevent in the forground
instead of as background processes, same thing happens.
I also tried not running irxevent at all, and just using keyboard. Same
thing.

So I tried running it on the same display, without doing the export
DISPLAY to the TV.
It worked!

Right now I'm working on finding out if there is a way I can better
'direct' things to the second screen, including keyboard input.

If anyone has any ideas on how to direct certain input only to a single
screen, or run things only on a single screen.. :)

Okay, cool stuff.
I export my display, and run Eterm &
That gives me an Eterm window no my TV.
I move my mouse over to it and start Mythfrontend there!
And everything works great, as long as I keep 'focus' on that window on
that screen.

So all I have to do now is figure out how to redirect irxevent signals
to a specific window!
And .lircrc files have that capabilit built in (to both window name and
window ID).
Once I figure out how that works, it should be all set.


As well as it's working now, I'm having another problem, but it probably
has to do with my not understanding what the buttons are set up to do.


Oh, and my resoution is kinda weird. I can't see probably a half an inch
of text to the left and top of the screen.
Will have to play with resolutions somehow :)

Thanks for your help folks. I'm sure I have a ways to go still, but I'm
on my way.

Myth is (currently) heavily dependent on focus. It processes input via X
keyboard events, which only get sent to the window with keyboard focus. It
may help to make sure your window manager is set up with a "Click To Focus"
policy rather than a "Focus Follow Mouse" policy. And yes, irxevent can send
events to specific windows, but there are many different windows in Myth and
you'd have no way of knowing which one was the "current" one. Basically,
Myth will not respond to any keys (whether from the keyboard or irxevent) if
it doesn't have keyboard focus, period.

I have had success!
By running Eterm on the TV display and keeping my focus away from it
fixes the keyboard problem.
The main good thing that came out of this is the modification of my
~/.lircrc file
I changed the key targets from CurrentWindow to 'mythfrontend' (which is
the name of the window).
And it works great! playing on my TV is live tv, and only the remote can
control it, unless I move my mouse from my monitor off to my TV.

So that's perfect!

Everything is coming along nicely... too bad I can't get the darn thing
to change channels :(
