satellite and cable video/audio. I now have an HR20-100, and it has been great. But I am tired of not being able to get my locals in HD. So I am breaking down and adding Comcast for my HD locals (I will also get CSS...a regional sport station available only on Comcast.) My problem is I run all my audio thru my receiver--no problems with additional outputs there. But my video is thru my projector, and between the DTV, DVD, and my computer, I am out of inputs. Now, I probably use my DVD the least, so I was thinking I could combine it's output with my computer as 1 of the inputs, and keep the other two for the two DVR's (DTV and Comcast). Setting up a program to switch things should not be hard since I have a harmony 880 remote. But what kind of "switch" do I use to alternate from 1 video input to another? Does this make any sense? Thanks in advance for your help, as I am in NO way an expert, but I can follow instructions pretty well, lol.
