Component video/RGB and VGA are analog video signals while HDMI and DVI use digital signals for video. The difference between them is that HDMI also carries audio while DVI is video only—the video signal of both is identical and you can get cables with a HDMI connection at one end and DVI at the other but they will only carry video.

You can't connect a HDMI or DVI cable directly to analog video outputs. Many new receivers will convert analog video inputs to a HDMI output so you can connect both HDMI and analog video sources to them and run a single HDMI connection to your display, but the receiver has to digitise the analog video signal in order for this to work.

The simplest hookup would be to use RGB connections from source to display.
