I am running XBMC on my Toshiba Laptop (Win 8.1) and looking at including Live TV, but need an external TV Tuner to accomplish this. I assume that the TV Tuner would need to be connected to my digital STB through HDMI to get the best picture.Any ideas or recommendations?If you need any more info, please ask. Maybe it is not a Tuner that I need, just a Video In box that will take the signal from the STB ???
