I'm putting together a HT system and have a question about video switching. First, an overview of my video sources: 1) VCR - Standard RCA connection 2) DVD - Component connection 3) Cable TV - Standard coaxial The receiver I choose will have video switching capabilities. How does this work? Will all video signals go fom the receiver to the TV via a component cable? I guess my goal is to leave the TV video input set to one selection no matter what video source I'm viewing. Is this possible? Thanks!
