If you click on TV networks there are some that will let you watch Live TV, such as Disney Channel etc. but what a pain to have to click on each network to see if there is a live stream avaiable. Seems like the easy of watching Live TV is geared more toward Tablets and not PCs. We have the Fios IPAD for the Ipad and that works but like you said, the same is not available on the PC.
