Which one is right for me?

I just want to access the MKV files and other content only that i put onto the USB Hard Drive.

The difference between the WD TV Hub media vs.  WD TV Live Plus is they are both identical with the exceptions of the WD TV Hub Media has a built in 1tb drive and you can network it… is that correct? any  differences? in speed etc?

I was hoping to fins something from WD that allows me to stream from the downstairs HDTV to the upstairs HDTV… is that even possible? If so what would i need for the upstairs HDTV to make that work?

I’m so confused. Please advise.
