I think it's easy to "overload" the CPU in the player if you hit too many buttons too fast - i.e. ask it to process too many commands in a short time. That being said, it seems to freeze up for no reason doing chapter skips & FF sometimes. In fact, the very first disc I played froze the player when I tried to skip chapter. Not a good way to start off. It'll be a long while before I buy another one, though. They have a long way to go to make BD players even decent - I feel like a beta tester.
