Buzzing indicates a ground loop. Mismatched impedance will manifest
itself as weak/loud/distorted sound.

Google for "audio buzz ground loop".

Thanks for the pointer. In this case the DVD runs off of the inverter @
120V AC and the stereo runs off of 12V DC. Are you suggesting placing an
isolation transformer on the DVD player?

Thanks for the info. I'll give it a shot when I get to the boat.
