Adjusting the overscan seemed to help a bit, but it still doesn't seem
quite right.  I managed (via VNC, so the image resolution is horrible)
to capture a still image of the video I am getting
(http://www.wesmo.com/Myth.png), and you can see the black bar at the
left side of the image.  All of the channels are recorded that way.  It
is as if the image is shifted slightly to the left.

Now, I don't have this problem via the Tivo (I had to resurrect it since
I wasn't 100% ready to switch everything over to MythTV) or any of our
other TV's via the DirecTv RCA set top box that we have.

Is this, possibly, something with the PVR-150 that needs to be set on
the backend system?
