fahrv asks: "I use a MythTV-based Linux PVR. I'd like to see if there are ways to implement automatic Tivo-like program recordings based on personal preferences (and Amazon-like analysis of what other people recorded based on what you've recorded.) I know that the Amazon patent on 'Other people who bought XX also bought YY' could be an issue, but then Tivo is able to record shows opportunistically as well. I don't see any technical hurdles to doing this by analyzing people's MythTV viewing habits in an opt-in kind of system; I'd be interested in building one. Might any of you have some thoughts on this subject?"
