Query: problems too

I too have had problems with the DVD-511. I have noticed it skipping at least once during each and every movie that I have played, sometimes worse than others. Other than that, it is a great machine. I am planning to take it back to the store I got it at and try another unit of the same model. If that doesn't make a difference, I will be getting an entirely different model.
