The Shifted Librarian says Maybe I Won't Try a TiVo After All. This is somewhat of a silly IMHO. I'd noticed this tendancy ages back. When I'm up late and can't sleep I'll have the TV on with no sound. I noticed it switching way back even when they used to have that little TiVo show that it would record. I personally think it's kind of funny seeing where my TiVo ends up when I turn on the TV (and it is rarely on the Discovery Channel, it's usually BBCA).
On another TiVo note, one of the things on my wish list is now a new TiVo. It looks like they are going to be doing some really cool thing with the Series 2 (including working with Apple for Rendezvous support). Though, if the hardware is basicly the same, I wonder if they'll support people with hacked machines. That would be a kind of cool upgrade to be able to do.
