CTRIBBLE:
YOUR RECEIVER CONVERTS COMPOSITE & S-VIDEO TO COMPONENT INTERNALLY!
That means that if you hook up a VCR (composte video), a camcorder (s-video), a game system (composite), some security cameras (composite) - The receiver will take those inputs, change them to component video, and output them to your display device.
There is no need to run extra cabling, there is nothing more you need to do for cabling other than hook up the devices to the back of the 3805. Transcoding video from one cabling standard to another is now included on a fair number of A/V receivers and eliminates the need for the extra cables.
NO NEED TO RUN MORE!
