I have tried different AV jacks and it still makes the noise, I've also tried using different inputs on the TV and all of them cause the buzzing noise when the DVD player is turned on. It still buzzes when a DVD is player, though not as loud until a scene break. I tried attaching a different DVD player and it made the same noise on all the inputs as well, however, when I attached my VCR there was no noise, and there's no buzz when I'm watching cable. Any ideas?! I'm totally perplexed!
