Hello- Mostly pleased owner of a new Sony Google TV / Blu-ray box. One concern that is irking me. No matter how many times I set the overscan to match my screen's size (the exercise wherein you press the up/right/down/left buttons to make sure the GTV screen covers the entirety of your display), the overscan stops covering the whole screen after several minutes of use. Switching channels, using apps, etc., inevitably the GTV display starts not covering the entirety of the screen or, worse, shifting slightly off center. It's hardly an experience-destroying problem, it's just very irksome. Anybody else have this problem and any solution? My GTV box is connected to a Tivo Premiere and my Panasonic Viera TV. I haven't (as far as I can tell) had this problem with any other boxes connected to the TV.
