Oh oh...
A whole bunch of views but no comments... I must have done something
really wrong...

Any guesses why mythbackend causes live tv to be played on the tv?

I must say, I love Myth...

I am nearly there with the setup, but have some silly things happening.

What I am running
AMD 2.0g
Redhat 9  kernel 2.4.22
Matrox marvel g400-tv

I am trying to use the g400 for capture and tv-out via frame buffer.

I followed many how-to's and here is where I am.

when I boot up I maually load modules :
modprobe -k i2c-matroxfb
modprobe -k matroxfb_crtc2
modprobe -k matroxfb_maven

I then switch the to tv:
matroxset -f /dev/fb0 -m 0
matroxset -f /dev/fb0 -m 3
matroxset -f /dev/fb0 -o 1 2

 ...and my TV displays my x-session!! life is good.


 When I then run iv4l1  I lose my tv out :(  and cannot get it back.

 Even more puzzling is when I then start mythbackend, I get live tv out
 my tv, no menu, mythfrontend,  not loaded.


 FYI, If I switch modes back to matroxset -f /dev/fb0 -m 1 I can then
 myth fine on my monitor.

 I am also trying to use alsa as described, but it is not all the way
 yet...  :)



 Any thoughts?
