What sort of cables? "RCA" or Composite (red/yellow/white wires for video/audio), Component (six wires, various different colors), optical (skinny round cable, you can see a red light in it if you look carefully, the port probably has a cover over it that's square), or HDMI (flat, sort of like USB but wider and thinner, connects video and audio)?

Consider the position of the TV relative to the DVD player - the magnetics can cause interference in the cables, if they are analog (Composite), or even in the speaker directly. That's a common one (was for me last time I set up a system with analog cables). Also could be the connector(s) themselves - try a different cable if you have one.

Kiwi ingenuity to the rescue.

What you will need:
Tinfoil
Copper wire
Cat
Coat hanger
Brick

Instructions:
Wrap the cat up in the tinfoil, tie one end of the copper wire to the cat; place the cat on top of the DVD player. Tie the other end of the copper wire to a metal door knob.
Place the Brick near the door knob and stand on it with one leg, hold on to the door knob, while at the same time holding the coat hanger in the air with the other hand.

That sucks! We just bought the dvd player about three weeks ago brand new. It's like a loud buzz or hum. Yes we have the yellow red and white cables using those. Our tv and dvd are right next to each other maybe we should move the location of the dvd player. It's really annoying to try to watch a flippin' movie and get this buzz in your ear.

It can be so many things.

Is it a hum or a buzz? A hum is likely a simple grounding problem. A buzz could be lots of things.

I assume this noise doesn't happen under any other conditions...
