I am posting this to hopefully relieve frustration for other Charter users. There is an advanced feature menu in most series of the Cisco/Sci Atlanta cable boxes that seems unpublished and which seems to be unknown to the phone tech support.
You gain access to this advanced menu by pressing "Settings" or "Menu" TWICE on your remote to get to the "General Settings" screen, then pressing "A" to get to Advanced Settings.
For HD users the Advanced Settings menu provides a number of important features including:
1) Setting the HDMI output resolution
If you are getting a flicker every few seconds in your HD display, your box may be failing to autodetect your HDTV. This is a known problem with some TVs, but no one seems to have written about it. The solution is to set the box to only display your highest resolution, i.e. don't give it any choices.
2) Setting the HDMI letterbox behavior. My box was set to show light gray borders on the letterbox and it was really annoying. You can have bright bars or dim (basically invisible) bars.
There are lots of other important settings here. The official documentation for the 46xxHDC series boxes mentions the access method only indirectly and only for an HDMI audio setting but otherwise doesn't explain how important it is for you to know!
