No, it has nothing to do with resolution. I am not sure what you think
overscan is. I suggest you read up on it:
http://en.wikipedia.org/wiki/Overscan. Your TV either overscans or it
doesn't. Some newer HD sets will have a setting to turn it on or off,
or may change it depending on the input. Almost all CRT TVs overscan.
The only difference is by how much.
I just use mythtv's built in screen size settings or wizard to adjust
the picture. You can scale the picture in either dimension or you can
shift it with offsets to move the offending pixels out of the viewable
area. Again check out the screen size wizard or look at your settings
