[mythtv-users] PVR-250: sound, NO video, no obvious errors,
' is the italian translation of the term 'Water'. This is what I'd
like to reproduce. :) PVR250 mythtv=sound w\ NO video,
record-v4l2.pl captures perfect sound and video ((help))

xawtv won't work with the 250. Try using mplayer
# mplayer /dev/video0
If that works you probably don't have a driver
problem.
You can also try playing video out of the ring buffer
while mythfrontend is running to see if it's a
frontend or backend issue.
# mplayer /var/video/ringbuffer.nuv
