I'm in need of a media player to replace my old egreat r1. Its slow and starting to have issues with newer codecs 1080p etc.

Heres what I want.

Fast menu system, able to ff and rwd with no issues on 720p files.
Network wifi so I can grab files off my PC or read files from my pc

I dont really need any tv services. I just watch tv series mostly.

Any recommendations?
