If you watch a recorded event, and then press stop and delete it, you get the following... The DVR Record Event screen with the inset window in the top right. The top 3/4 of that window is filled in solid gray. Behind all of that a satellite channel's video is playing with audio. You can see through around the edges and in the bottom 1/4 of the "pip" window in the top right. The video that is visible has funny little horizontal stripes through it that seem to match the pattern of the background of the DVR Record Event screen.
