Any suggestions as to what I have to do to make this work?

Get a 12v DVD player. It's the inverter causing you the trouble. I'm not
at all confident that you'll be able to effectively eliminate it on the
boat. I've got a 12v player in our 348 Vista and it's great. I actually
use the AUX-in on the DVD player to daisy chain input from an iPod.

That and you're likely to get better battery life using a 12v player anyway.
But if the player already uses an external power supply you may be able to
use a DC-to-DC transformer to adapt to whatever voltage it needs. But if
you want to just cut to the chase and get things working I'd dump the
AC/inverter setup and just get a player designed for auto/rv/marine use.

Having the TV & DVD player running off the 12V without using an
inverter has other benefits, like less power consumption and a quieter
environment in the boat, but my experience is you can still get these
ground loop problems. I had both my TV (Went thru a DC to DC converter
to boost up to 18V) and a 12V DVD player side by side connected to the
same 12V outlet, and still needed an isolator on the line between the
TV and DVD player. In fact, I think it was recommended to me in this
google group.
