very nice, very clean.
My only critique is that it feels a little too predictable. It feels like something that I would expect to see coming to market right now. I think you can push the boundaries further starting with the interaction concepts, then the visual design, and definitely the remote and hardware. When I was at frog I lead a team that did a next generation smart TV physical/digital interaction hardware/software design project for a large brand and there is a lot more room for you to push further. Focus less on making the presentation look like an existing product sell web experience and blow us away!
