Go into the menu of your Directv receiver. Select Setup, System Setup, then HDTV. Turn the Native setting OFF. Then move to the Resolution tab on that page and make sure that 1080i and 1080p (if available) are the only two resolutions selected.
This should stop that popup banner and make channel changes much faster.
Every time you change stations (that change from 480 t0 1080, Example), the infor box comes on in the upper left of screen andblocks out the directv information. Can this be moved or turned off?
