Of course it depends on what kind of video cables you plan to input and output. I'm using a DVDO Edge video processor and switcher that accepts various kinds of inputs, but only outputs HDMI. AVS had a group buy on the Edge, and I've been very pleased with it -- a single button lets me switch both audio and video between my DirecTV HD-DVR and PS3-80. If your video display accepts HDMI, I can recommend the DVDO Edge.
