I was watching my Lion King blu-ray with no problem whatsoever, but later on when I go to watch it, it remains on the Walt Disney Castle screen and will do nothing else except allow me to go back to my blu-ray menu, and when I press play, it shows a timer that ends at 18 mins and 7 secs, then after that it just seems to freeze (water stops moving I should say). Is there something I can do, or should I just take it back and get another one?
