I've had my 575 a couple of weeks now and last night when watching Whale Rider it got to a point on the disc where I think the layer change should have taken place and froze. This was about an hour into the film. No later chapters would play either. The disc played fine on another machine and at the point it froze on the 575 there was a slight pause and then continued playing. I think this is a typical artifact of a layer change taking place. Has anyone else had any similar problems?
