What's the role of the receiver in playing DVD's on the ps4 compared with games and Internet video's?
I have a Samsung HD TV, and a yamaha receiver & surround sound. When I play dvds the picture I get is a green/pink. I have both a ps4 and an LG hdmi dvd player. The same issue present in both. However I can still play games and Internet video using my ps4 and picture quality is fine. What can I do?
