movie channel line up

When I go to the movie channel guide (not the on demand movies guide)  there is a problem with the movie guide displays not tiling properly.  It displays seven movie selections per line but the movie selection to the far right on the screen is cut in half since the entire display is not centered.  The display has a gap on the left side of the screen and this causes part of the movie guide display on the right side of the display to be cut off.  I have had several techs out here and replaced my box to no avail.. I have also checked other Comcast X1 customers in the area and they are experiencing the same problem as I am.  I was told by the Comcast techs that this is not an equipment issue but a programming problem.  I have reported this over 5 weeks ago and the issue was never resolved.  Please respond.
