Re: Channel PIP Preview window not all channels show a preview
It depens on the channel and the time
Any show that you highlight in the future will show a blue screen with an image of a white clock in it in the PiP window (to referr to a future aring), any channels you are not subscribed to will show up as a blue screen with a picture of a white TV in the PiP window (you can always hide these channels if you wish), then on sports channels (mostly currently unused alternate networks or blacked out games) will show up as a black screen with a picture of a white TV and a message saying that the channel/event was blacked out or not currently being used, in the PiP window, the two last ones will show those screens fullscreen when you select to view them
