[mythtv-users] making capture a real 640x480-getting rid of blackbars

[papenfuss at juneau.me.vt.edu]

	I've looked through the ivtv source a bit, and it looks like there's 
some hard-coded "black border" #defines in there that have been mucked with in 
the past.  You could take a look at that.

	I've noticed very small black borders on mine, but haven't had the time 
or ambition to play with it.  What's been cut out is normally overscanned out 
of the picture on the TV anyway.
