Well I won't mention how I think you should feel after having spent $400 on a little piece of plastic
I can understand feeling frustrated, but until you've called panasonic I can't see anything more then that....in all likelihood, when you call them they will be perfectly happy to replace your disc and then you will feel better

Technology doesn't always work the way it's supposed to, that should be expected. As long as the maker of the technology is willing to put things right, you shouldn't get too upset.
Now if you call Panasonic and they tell you to @%&* off, then you can feel violated
