i dont use video switching through my receiver (though i have had to in the past), but i think most people want it. depending on how much gear you have and how nice of a tv you have, will dictate the need. it is safer to put it in rather than take it out for sales purposes. i think there is a convergence of audio and video rather than a divergence, hence the term home theater.

plus who knows what will be the next great thing requiring another input that you dont have available on your tv.

its not like we would be saving any money without the video anyway.
