You only need 2 things, the program xbmc and the addon pvr.vuplus.
The folder pvr.vuplus goes in the addons folder of xbmc on your pc, then you can activate it through xbmc and configurate it.
You only have to know the ip-adress of the Vu, where you`re channels are placed and your recordings.
But i have not got a clue what you want to do or achieve with the Tuner Server.
