That doesn't change things.  The following commands all cause a green
box to be displayed:
  
  mplayer tv://
  mplayer tv://3
  mplayer tv://3 driver=v4l2
  mplayer tv:// driver=v4l2
  mplayer tv:// driver=v4l

I don't believe this card has a tuner.  It only has two physical
ports, an RCA and an S-Video, both of which are inputs.  And it seems
they are considered the same port internally.  

Is it your understanding of tuners that they demultiplex one signal
from many coming in on a coaxial line?  Since this card just has an
RCA/S-Video input, I believe it inherently requires an external tuner
to ensure that there is only one signal on the line.  If I'm right,
then there is no tuner at all.  My cable box has an RCA out, so I
guess there is no need for a tuner in the PVR.

All those input numbers give the same results: a green box, and the
following output:

Those options result in a green box as well.
