Hello, this is outrageous.

Philips bluray decks fail after 2 years of moderate use (for me 60 hours of use), they indicate "unknown disk", full of French users talk on web forums dedicated French.
This should be supported even out of warranty, it is a manufacturing defect.
Car manufacturers do it well. We buy philips thinking have quality and it was a nasty surprise after 2 years of purchase (I bought my bdp5180 in 10/2010).
Indeed, my deck starts to indicate "unknown disk" on some discs bluray brand new (which were read carefree few months ago). I installed the 1.62 update yet., and my discs are europe area.

too disappointed
