For the past (well, see for yourself) few days I've run my Tivo without the pleasure of an attached phone line. Tivo can't phone home to report to Tivo Central on my viewing habits. (It can't update it's software either - fun when changes happen like different Daylight Saving times.)
I wanted to get a picture right at 1000, but I just don't watch enough TV. The cause of this rebellion isn't just my not wanting to feed stats to Tivo (I don't much care), but this Tivo device won't work over my Vonage.
