Hi,

I need help (once again ;)).
I'd like to use MythTV to watch TV with my WinTV-PVR 250 card.

IvyTV is working fine, I can make a capture when I want using cat /dev/video 
>test.mpg. For the moment, I'm just trying to see input from my VCR... So I 
made a test_ioclt -p 6 (to select the S-Video0 input of my card)
- BTW, is it necessary ? Does not MythTV do this alone ? Because if MythTV 
does not, I'll have to switch manually between S-Video0 and Tuner input. But 
that's not the point...-

So, cat /dev/video0 show me the output of my VCR : cool. 
I run mythbackend & mythfrontend. Here are the logs :
(megan is localhost : 127.0.0.1)
/usr/local/bin/mythbackend
Starting up as the master server.

As you can see, there is not error message. But I've only a black screen (with 
a very quick blue flash a few seconds after starting Watching LiveTV).
About MythTV setup :
The device configured is well the /dev/video. The MPEG2 decoder (for WinTV-PVR 
x50) is selected. I have a video source named "video", (using "NULL" as 
tv_grabber,) and an input connection between this video source and the 
S-Video0.

I don't see what's wrong. What should I try ? If you need more info, simply 
ask...

Thanx in advance :)
