I'm using the latest official FW, not the newer beta.
As a quick test I tried loading Once Upon a Time in the West, comparing my BDP-83 vs the BDP-95. I turned on both units, immediately opened the tray, inserted the disc and closed the tray. I started timing when I pushed the button to close the tray. My modem was off.
Time to the beginning of the Paramount logo:
BDP-83-- 52 secs.
BDP-95-- 61 secs.
I always disable my network to my players unless I need it. It causes too many problems.
