I notice the screen has no device node specified.  So just to ask the
simple question before we look further: Have you tried specifying 

/dev/video0
or 
/dev/video1
or etc.

for video device?

If you have, does the device node have the proper permissions on it?

I have mine setup like this as the mythbackend isn't running as root on
my machine:

$ ls -al /dev/video*
lrwxrwxrwx  1 root root        6 2008-06-17 06:17 /dev/video -> video0
crw-rw----+ 1 andy mythtv 81,  0 2008-06-17 06:17 /dev/video0           
crw-rw----+ 1 andy mythtv 81,  1 2008-06-17 06:17 /dev/video1
crw-rw----+ 1 andy mythtv 81, 24 2008-06-17 06:17 /dev/video24
crw-rw----+ 1 andy mythtv 81, 25 2008-06-17 06:17 /dev/video25
crw-rw----+ 1 andy mythtv 81, 32 2008-06-17 06:17 /dev/video32
crw-rw----+ 1 andy mythtv 81, 33 2008-06-17 06:17 /dev/video33

The even numbered nodes are my ivtv/PVR-150, the odd numbered nodes are
my cx18/HVR-1600.


If all that's good, what do the error messages mythtv-setup outputs to
the terminal screen say?

Andy
