You can get Youtube and Hulu via Serviio, and unlike Playon, it's free. IIRC, there have been some reports of Serviio working on Hopper, but I haven't been able to get it to work on mine. But I don't have a HIC.
Since DirecTV has Youtube, I would expect Dish to offer it at some point. Personally, I find my blu-ray player does a much better job streaming than DirecTV or Dish DVRs.
