This just in: MythTV can still be a pain in the ass to work with.
I've tried it multiple times, I've gone back to my TiVo Premiere every time. I work on computers and build servers for a living. I'm used to banging on computers to get them to work. But that doesn't mean I want to do it just to watch some TV when I get home. I don't give a crap about games, because I'm not a gamer. I don't give a crap about networking to other TVs, because I live alone and only own one. I don't give a rat's ass about OTA because I live in the country.
I bought the TiVo, drove over to my cable office and got a M-card, brought it home, took the TiVo out of the box, plugged in the M-card, hooked up the cable, powered it up, went through the initial setup, and its worked flawlessly since Day 1.
