That's what I thought too, then I looked at the original post and only about 20 people responded (really surprising). So there wasn't much interest and perhaps he felt it wasn't worth the effort.
Cable companies want above else for you to use their hardware and their services (DVR, cable box, etc) and are still fighting tooth and nail to cripple competing services on every front.
Well, too bad for them that they can't force me to subscribe to cable. I've even gone so far as to pull out the janky wiring from multiple cable installs over the years in the house I purchased.
