Grainy Picture Denon 1740 DVD and Samsung 1080P...

Question

I just bought a denon 1740 dvd player. I have hooked it to my 40" Samsung 1080P and it appears grainier than my last cheap dvd player, i am wondering if I have some settings wrong. Even animated graphics seem to jump a bit. Is there a setting or anything else you thik I should try or is this just a result of something wrong with the hardware,
