Hello,
(sorry for my english, it's not my natural language, i am french)

I have the BDP7500, and i allready read Avatar blu-ray, but since the last firmware update, i can't read it more.
Can someone help me?
can i go back to older firmware? i try to find one, 1.52 or older, but didn't find it.
I try to reset the device, but it didn't reset the firmware.

does someone has the same problem?

All ideas are welcome...
