Look, this is not a slam on YAMAHA, in fact the reciever is very impressive, and the up convert function was a was a very impressive bonus function, with my set-up the picture was dramatically improved. I'm sure other company's put out products with defects, this is not an unique situation. To make a long story short without getting into the details I replaced the reciever with a brand new one, but, I will never look at it the same, each time I turn it on I will watch and see if there is any change in the video. Like most people I use it every day, and now I'm convinced that its just a mater of time before the same thing happens again. This is probably due to lack of any understanding of how this feature works. If the potential of this product wasn't so impressive, this would hardly bother me.
