Just bought the sony 37' plasma and, although it's a beautiful set, I'm disappointed with the picture. I've got it working off a Humax 40 gig freeview box but am getting a LOT of motion blur and granularity. Not sure if it's the TV, the digital receiver, or both!! The Sony Centre say it's the quality of the digital signal and that it would be a waste of time upgrading the scart cables. Does anyone have any suggestions at all. I was aware that there would be some degredation in picture quality from CRT standard, but not this much.
