I too had to do the firmware upgrade..105,106, and supposidly they have a 107.
My question is have you had the delay issues when switching from source to source, and also from standard def to HD channels on cable? Epson has said that R & D is working on it, but until I've had the fun in trying to explain a customer why you lose a picture for 15 seconds when you go from one game (HD) to another game in standard def. Not fun.
