I have a panasonic 5 disc changer. I notice some artifacts and pixelation on my DVD's with deep colors. Especially black. Is this normal? I have played iwth the picture settings which include...cinema 1 cinema 2 user and normal. Is black a normal problem for dvd's to display properly? I use composite hook ups to my Sony Trinitron TV...so I don't think its the cables. They are high end cables...any idea? Am I just whacked?
