    Can a digital coaxial cable be used to connect a VCR to a tv/monitor in place of a standard RCA cable? standard RCA cables look so weak !

    Yes. Really there are two properties with these cable types: Connector and Impedance. Obviously the connectors (RCA) are the same- the only other issue is impedance.

    A cable designed for sigital signal will be 75 ohm- this is the same desired impedance for composite Video cables- so essentially their identical. Audio looks for 50 ohm signal path, but popular opinion is that 75ohm will work just fine for audio without any ill effects.

    So, a basic answer is that Digital Coax is essentially identical to composite video cable, and will also work fine for analog audio connectors.

    PS: You said "standard RCA are whimpy"-- but I assume you mean the junk cables packaged with components... there are heavy duty RCA cables designed for each application (Heavy Duty Audio, Video, Digital, whatever).
