If you can cat /dev/video0 and get a valid stream then the driver is 
working.  If mplayer still displays blank video on /dev/video0 then 
you've got mplayer set up wrong (or there's some kind of problem with 
mplayer).  What happens if you do this:

  cat /dev/video0 >/tmp/foo.mpg
  # Wait a little while then hit ^C
  mplayer /tmp/foo.mpg

Do you get useable video in that case?

When the HVR-1950 is in digital mode, the cx25840 is not used.  At those 
times it could potentially be fed an invalid input routing.  I've known 
about this for a while, but it's completely benign (and not trivial to 
fix) so I haven't done anything about it.
