I have had my Tivo HD for a few years and saw this for the first time this eve. Was watching Survivor (recorded), and during some commercials that advertised other CBS shows, a little icon showed up on screen that said "Press thumbs up to record". A search turned up a few posts talking about this from as far back as 2006, so it's not a new feature, but I didn't find any recent discussion. Is this a rarely used, or have I just not noticed it before? I'm not complaining about this feature. It was unobtrusive and seems like a cleaver advertising mechanism. If you are fast forwarding through the commercials, you probably wouldn't even see it. I was just surprised to see something "new" on the Tivo HD.
