I have a PVR-350, and I am trying (unsuccessfully) to get the mythtv
front end out on the TV video output. Can anyone help direct me as to
what the possible cause is?
I can get the TV channel video to output on the TV video output. The
system works fine if the X display is not send to the TV, but only to
the regular monitor. There is another front end PC, with no TV out put,
and this other PC works fine with the TV video and Myth front end both
in the same window.
If I enable the X display to the TV, then both myth front ends loose TV
video. Any recordings will also loose video, like the encoder stops
working when the X display is enabled.
With Myth stopped, this command results in video and audio to the TV,
when X to the TV is turned off.
dd if=/dev/video0 of=/dev/video16 bs=16k
When X to the TV is turned on the PC locks up, no mouse, keyboard,
network, and the regular monitor freezes.
If X is started first, then there is no TV channel video on the TV output.
The setup is Mandrake 10.1, with a custom kernel based on 2.6.8. I am
using ivtv ver 0.4.0 and the X module ivtvdev_drv.o.
