I almost never watch DirecTV these days because i use itunes and hulu. I use my PC and now my iMac for music and movies. I would like to try and move completely away from DirecTV.

If i list my wants/needs can you guys tell me what to research? Or how to do it as painlessly as possible?

1.The ability to view & schedule recordings for OTA HD (free locals).

2.The ability to view & navigate hulu.

3.The ability to navigate Pandora or other free internet radio.

4.Something like iTunes (or whatever service will work) where i can buy-download-watch on demand music and movies/TV.

5.Ability to control the built in DVD drive on the iMac

I am looking for an integrated solution. 1 remote, 1 interface would be perfect :). Please tell me about my reality based options :).
