Wireless Media Player HELP!

Ok, here's the setup:

PC in location A. PC is hooked up to a wireless router via ethernet cable. 1TB external hard drive is hooked up to PC via USB cable. Downloaded and backed up media content is regularly copied from PC to external hard drive.

TV in location B. Has HDMI inputs and lan input etc., it's a new Toshiba 39".

What we are wanting to do is play the media from the external hard drive on the TV, wirelessly.

Now, we've found a few decent looking Android wireless media players on eBay, a few of these are:

- http://www.ebay.com.au/itm/190831672144
- http://www.ebay.com.au/itm/400442463493

My question is, can we plug any of these media players into a power outlet in location B where the TV is, and then plug the media player into the TV via an HDMI cable, and connect from the media player to the external hard drive (plugged into the PC in location A) to see and play media files on the TV?

Or by "wireless" media players does it simply mean they can connect to the internet to visit websites and maybe watch YouTube etc. on the TV through the media player?

Any help much appreciated :) We've asked each seller and haven't heard back so need to find out before we buy in case it doesn't do what we are needing it to do :)

Thanks guys!
