[mythtv-users] Setting overscan with PVR-350 TV out?

I believe it cant be done by any other means than reducing the pixel count.
IVTV can't do it at the moment but when it will be able to all it will do is
reduce the pixel count as well so using things like ratpoison will achieve
the same thing.

But if you really believe the PC software can do this for the 350 then that
is interesting since maybe there is something that we've missed. However I
have no idea how we would do this at the moment and I don't believe anyone
else working on ivtv knows how to either.
