My computer and dvd player wont play the last 10 min of this dvd. My dvd player just freezes and my computer says that there was an error that it may be scratched or dirty. I looked at the dvd and at the edge, there is a light scratch... I've certainly had worse in my cd's and other dvd's. (not that I don't take good care of them...) Anyway, I tried to clean it a dozen times and even tried the toothpaste method.. No luck. Is there any other remedies you'd recommend? I'm not kidding about this scratch, it's so light that at first I didn't even think it was the reason for the dvd stalling. help please?
