Comcast
 

Ever since Comcast took over in my area a month or so ago,my wide screen tv now has lines down each side framing the screen?
I have a full screen picture but on each side, six inches of the screen are a lighter picture.
I know when shows were not in H D that same area would be black.
Now I have the lines in reg and HD?
Has anyone had this happen, just wondering if it is the tv or Comcast?
