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.

I've been through about 3-4 DC based DVD players and haven't found
one that compares to the AC based Sony that I settled on. The Sony
plays everything flawlessly. I'll work on it from the isolation
standpoint. If the problem is a ground loop, it seems that there's
no reason to assume that the isolation transformer won't solve it.

Geoff,
Do other audio devices work with the stereo on the same input you are
using for the DVD? Maybe the problem is not with the DVD but is with
the stereo.

I feed my Sirius radio and SSB (so we can listen to the nets while we
have breakfast in the cockpit) through it. Both are fine. I have an
isolation transformer on order which will be waiting for me in Ft.
Lauderdale when I get there next week.

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.

Ahum, this is NOT a google group. You may be reading it through Google,
but the USENET predates Google Inc. by a few decennia...

Try googling for "usenet is not google groups" :-)

Interesting ... is google groups a good way to view this group, or are
their much better ways to do this ?

I'm on the boat in Ft. Lauderdale and I'm happy to report that the
ground loop isolater worked like a charm.
