I have a Optoma RD50, with a sony DVD player, with component out connected. I've had no problems with it before this, I have found that newer DVDs have this problem where the top first inch of the screen is like a waves/zig zag. It looks fine on all video games, and other DVDs. I even tried the same DVDs on my playstation and the same effect, maybe alittle smaller but the same effect. Any ideas on how to fix this. I've change the setting on the DVD player from 16:9 to 4:3 and back.
