TV Not Displaying Full Picture

I have a TiVo Roamio Pro hooked up to a Vizio 55" LED. I've noticed that when watching shows via the Amazon and Netflix apps that the screen is wider than the TV. I checked all the TV settings for Zoom, Normal, Wide, and Stretch. When on Normal, the picture is the widest, but is still not wide enough.

Is there some setting on the TiVo that I need to set as well?

Thanks.
