Go to the "Now Playing" list, then press Slow, Zero, Record, Thumbs Up. This'll pop up a menu that'll let you select sort-by-alpha, -by-expiration, and -by-record-date (normal). The cool thing is that you don't have to hit that long string again. It just turns on the sorting method, and you can get to it via "Info" or something like that from the "Now Playing" list (it'll say at the bottom of the "Now Playing" screen). Even cooler, you don't even have to go to that menu again. You can just press 1, 2, or 3 to go directly to the different sorts. And, unlike most things on the TiVo, it doesn't take an hour and a half to perform.
