I have installed Windows Media Center in Windows 8 Professional and now I wish to use with other Windows 8 pcs -WMC as the media centre hub,I know it can be done with XBox but I like to enjoy Live tv.
First thing-you can NOT use a PC as an extender.
Alternatively you can try network tv tuner as found at http://www.silicondust.com
You may also look for DVBLink
This will allow you to watch live and recorded TV programs in Windows Media Center throughout your house on DLNA devices.
