Hi,

All (most?) TVs will overscan by a few percent.  In fact, this is
something I recently learned about, and was told it was normal.

I discovered this while doing compression testing.  I encoded a clip
from a movie, paused at a certain point, and paused at that same point
using my DVD player.  Then, I'd use my A/V receiver to toggle back and
forth to examine the differences and compression artifacting.  That's
when I noticed my DVD player outputted a picture that seemed to be
zoomed in slightly.  Or so I thought.

After some investigation I learned that it wasn't the DVD player that
was "zooming" but rather my TV.  The overscan setting on my video card
(via nvtv) was such that I was able to see the _full_ video frame; the
overscan done by the video out in combination with the tv's overscan
rendered the full image to my TV.  And I never really noticed the
difference with my DVD player until I tried the A-B test.

So if you want to adjust for this, you'll need to do the -vop expand
trick, or you can try adjusting the overscan on your video card's
tv-out, if that option is available to you.

Cheers,
Jason.
