Did you manage to get a hold of this firmware? I'm looking for it now...
I upgraded to the 1004 version of the firmware to stop the IR problem. But now I have major clouding. It is not just me. In the Avsforum.com's 850 owners tread a bunch of people have complained about the clouding appearing after the upgrade.
I just want the 1002 or 1003 version back. Where can we all get it from?
