Buy a cheap USB HDTV tuner. Install MythTV. Start watching all 1 hours shows 20 minutes late. Then let MythTV skip commercials for you automatically.
Seriously though, I have run it, even debugged the channel changing under Linux and stopped it hanging up, but sadly I live out of range of a decent HDTV signal for right now.
