Deleting a recorded program is similar to deleting an app from your tablet. Tap and hold the program you wish to delete. When the X with circle around it appears, just tap it. If you are unable to delete a program, your receiver may not be set to allow programs to be deleted. At your HD DVR, Press MENU on your DIRECTV remote, then go Setup->Whole-Home->Share Playlist->Allow Deletion and select From All Rooms.
