In my setup I try my best to route each video source directly to an input on the TV, and let the sound be switched by my receiver. If a device has more than one output, I'll usually let the second go through the receiver and then to the TV just to have an alternative path in case the highest-res one fails. With a PIP TV, I can then compare the same content via two paths, and it's easy why the straightest path to the TV is always the best.

My next upgrades will be to pure digital paths for all content. Can't hardly wait! ;-)
