I ghuess I need to vote and comment since I have had a replacement. I saw now improvement in PQ, either HD or SD. I saw no difference in the Darn Picture bud in SD from S-video. I can not lock any station that I couldn't lock before. But a couple of stations that I sometimes had to stand on one leg while pressing the View button with my nose then hit info with ,,, Well they now lock almost immediately, almost all the time. The other stations do lock a bit faster. That is the only difference that I see.
