Hey guys, I have a question. Since I don't have another Blu ray player to check, can anyone tell me if there is a way to tell if a problematic disc is the result of firmware or defects in the disc? ( I may try the disc on a friend's player) As I said above, I just updated the firmware on my Sony BDP S550 since the discs would not play. After the update, all the discs played. But since I am finding Long Live Walter Jameson is freezing momentarily at specific points and I see pixellation when it freezes a few seconds later. It occurred to me that pixellation might be a clue that it's not firmware, but a defective disc. The disc appears to be clean and I don't see any scratches. What do you think? I am very tempted now to exchange the set.
