[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))

[Joel Cooklin]

I can't figure out why through mythtv I don't get a picture.  When I 
playback the result of  '/usr/lib/ivtv/record-v4l2.pl -c 3 -t 1200 -D 
/stor/stage' I get a perfecet picture with sound.  However through 
mythtv I just a blank screen with sound.  There are no obvious errors 
being reported in dmesg, messages or on standard err of either the 
backend or frontend.  Probably related is the fact that I am also unable 
to get any kind of output through xawtv.  I would appreciate any help 
that could begin pointing me in the right direction.  Below is some 
information that may be helpful.  Thanks.
