Hi there, I've been noticing that a few of my discs have been having a problem with the Pioneer 575. A couple freeze in parts of the film (there are light scratches, but play fine in my PC dvd player). A couple of others, such as 28 Days Later and The Last Samurai (both R2) I bought brand new, and it is skipping on them. The Last Samurai sometimes refuses to load, and when it does, keeps freezing and stuttering when I browse through chapter selections. Anyone know what the problem could be?
