Hi. Since setting up my Google TV settop box, I've been noticing more shows and commercials are not completely filling my HD flatscreen's screen. Before Google TV I'm thinking that perhaps my TV, DVR, or Receiver was somehow up scaling these pictures so that they fill the screen. Is there some setting I need to change on my Google TV to accomplish this? I'm on the Sony settop box and TV is provided via Directv. Any thoughts would be greatly appreciated.
