Next version of Windows needs to ditch Windows Media Player and Windows Media Center.

 

Zune Software will replace WMP

 

Media Center needs to be replaced with a simplifyed Apple TV/Google TV solution, Zune TV which allows a zune pass video subscription, streaming or syncing of content, and direct ports for attaching DVR and Set Top Boxes.  Made by many manufacturers, which can be combined with Blu-Ray and DVD players, or just in simple streaming versions, with a plugin/app ecosystem, which can be developed in silverlight/xna.
