Search for John Wayne
. In the TV section there are three selections - an episode of The Beverly Hillbillies, and episode of I Love Lucy and an episode of The Lucy Show. If you select the first two you can see recording or purchase options, and you can then cursor left from those screens back to the John Wayne screen. If you select The Lucy Show the episode screen says "No Upcoming Showings," but there is also no way to exit this screen. Any cursor key gives you the kettledrum error sound.
The TiVo button will return you to TiVo Central from this screen. If you then navigate back to Search Beta and search for John Wayne again, selecting The Lucy Show a second time takes you to a perpetual Please Wait... screen with no way to exit via cursor keys. The TiVo button again returns you to TiVo Central.
