Pogue posts something that was borrowed from the TiVo cheat code page (I guess Pogue never googled TiVo codes)
Pogues Post: Resorting Now Playing List:update 12/16/04: Actually, on my DirecTiVo (sic), 1 and 3 are reversed - 1 sorts by date, 3 by alphabet.
Turns out you can sort your Now Playing list, the list of shows that the TiVo has recorded and accumulated for you. If you have a Series 1 TiVo, or a DirecTV model, start with these steps:
Go to your Now Playing List (generally, that means pressing the TiVo or DirecTV button twice). Now press these four buttons in this sequence: Slow, 0 (zero), Record, Thumbs Up. You should hear three dings; that means it's ready!
(If you have a Series 2 TiVo, you can skip those steps and just jump to the good stuff:)
Now you can: Press 1 to sort the list alphabetically. This is a great feature, because it groups together all episodes of series shows.
Press 2 to sort it by expiration date.
Press 3 to sort the list by date of recording.
As a bonus, the mailing also offered a tip for Series 2 standalone TiVos, and the high-definition DirecTV HR10-250.
It’s a tip to jump to the beginning or end of the Now Playing list: the Advance (Skip-to-tick-mark) button. Each press of the button takes you back and forth between the top and bottom of the list.
Man—all these years. How did I live without these tricks?
