How do you feel about off-the-air? I used to use a Silicon Dust HDHomeRun Prime CableCARD tuner with Windows Media Center and Comcast cable. It worked, but it was honestly a bit of a pain in the ass and I was constantly playing tech support for my wife and kids. I dumped it for a quad-tuner Tablo DVR and have been much happier with it. The only caveat being I am now limited to OTA content. With the ability to watch and record all the major broadcast networks, plus subscriptions to Netflix, Hulu Plus and Amazon Prime, I have not missed cable at all.
I don't care about apathy
