I've noticed some channels coming through in a smaller format. It's like 16:9 but smaller. I've seen this done with ads but not regular TV very much. But after Comcast pushed out some updates back on 2/18 I've seen this more. Not sure pbbear if this is relative to your issue.
Your notes say you switched from 16:9 to 4:3. So apparently no matter how you set it you are not getting 16:9? What process are you going through to make this change.
The Guide and Menu items can also be displayed in 16:9.
Follow these instructions:

About the TV Aspect Ratio
The TV that you have connected to your set-top has an aspect ratio (width-to-height ratio) of 4:3 (basic/
standard) or 16:9 (widescreen). You must set the appropriate TV Aspect Ratio (4:3 or 16:9) on your set-top, so
that it is compatible with your TV.Setting the TV Aspect Ratio

Press the U or D button on your remote control and highlight TV Aspect Ratio on the USER SETTINGS menu.
1. To change the TV Aspect Ratio, press the R button.
The TV Aspect Ratio menu, shown below, appears on your TV screen. On the menu, the current setting
