Why does the high-definition video disappear when I bring up the Cox Interactive Programming Guide?
Due to a technology limitation of the Cox high-definition set-top, most graphics cannot be displayed over high-definition video. This means that the video will disappear when you launch the Cox programming guide or press the INFO button on your remote control while viewing high-definition programming. Similarly, emergency alert messages may cause the video to disappear when the emergency alert message is displayed. Also due to the graphics limitation, the volume indicator banner will not appear on your TV screen when adjusting the volume of high-definition programming (in order to minimize disruptions to the video programming).
