I just added the HD tier to my cable lineup. I've noticed a bunch of new shows that I would never watch in SD. Travel shows, documentaries, Reality shows with Meerkats, Wretstling meets Survivor in Last Man Standing, music concert series, Planet Earth... I find myself glued to the set. And, since I haven't sprung for the HD Tivo, I find myself watching a lot of shows live in real time. What are you watching on HD?
