On a PVR-350 output you will always have overscan and I believe that it
cannot be adjusted (might be wrong) however you can change your gui
size in the mythfrontend setup. It will take alittle bit of time
and having to traverse menus many times but you can get it pixel
perfect and it looks great.<br>
>From the main menu goto
Utilities/Setup->Setup->Appearance->Screen Settings(it is the
second page in). On that page you can adjust your screen size and
offset<br>
