Query: This is the worst dvd/vcr product that you could buy!

I first bought this last week, and when I played DVD's it made a loud humming/buzzing sound. It was so loud that you could barely hear the audio. I returned it, and decided to try another one just in case I had gotten a defective one previously. Well, when I set up the next one it did the same exact thing. I don't recommend anyone buy this product! It is by far a terrible machine, so avoid it if you can!!
