Being a BT broadband customer, I occasionally watch some BT Sport live broadcasts on my Desktop PC which is situated in a spare upstairs room. I would like to be able to display the picture on the family DTV which is in the downstairs lounge, but I am currently having a problem doing so. My wireless home network allows content on my PC's HD to be displayed on the DTV, but I cannot work out a way of displaying streaming video. I also have a 25m long HDMI cable that links the PC to the DTV, but once I connect the two, I have no way of controlling what is displayed on the DTV using the PC mouse, as I can obviously not be in two places at once. Any suggestions would be appreciated.
