Gray Bars On Sides. Tried both aspect ratios. - DirecTV DVR

For Gray Bars On Sides. Tried both aspect ratios., relating to DirecTV DVRs and receivers. I noticed last night that something had apparently happened to my display setup on DirectTV. I have a new 16:9 plasma that all of the sudden started displaying the gray bars on either side of the picture, including the DirectTV program guide.

It did not used to do this; all channels used to be full screen. Under Dispolay Setup, I tried both aspect ratio settings, but they both looked pretty much the same.

The only thing I've done to DirectTV recently was cancel my movie channel subscriptions last week (I went down to the middle package - total choice plus).

My anntena and DVD inputs are not exhibiting this behavior.
