My goal is to be able to watch local football games out of market at a second home. My main home has a DirectV whole house receiver. I understand that I need broadband at both residences. Can I stream live TV directly to a 70" big screen or must I route it through a computer which is hooked up to the Big Screen? What sort of video quality can I expect on such a large TV? Can I also watch other TVs in my second home with one Slingbox, much like I can watch different channels at home on different TVs? If so, how does one go about setting up additional TVs in a second home?
