I did manage to get the insulation off (good to know that it might help since I went to the trouble). One of my nice sharp kitchen knives isn't so sharp anymore. I appreciate the help. If the transformer is good for digital, then I'm set. The problem isn't installing a new transformer, or finding the other one I have, or even buying one (they are cheap), but its being build now, and since it wont fit on the entertainment center, (about 24 inches clearance to the ceiling and I need at least 30 inches with the rotator) its got to go behind it. thats nice because while I would put an ugly monstrosity on top, the wife wouldn't like it. there is plenty of room back there, but it has been intentionally blocked off with very limited access, to keep the kids out. Thats where I put computers when I am working on them for other people, but it takes 15 minutes moving stuff to get back there......
