I have a Samsung Blue-ray SD-P1600 disc player hooked up t0 a Samsung 1080p full HD flat screen TV. My internet provider is comcast. Even when I directly connect the disc player to the router via ethernet cable, i can not view Netflix in HD. I noticed that I can occassionally get HD in the day time but not at night. The transmission speed is however showing at greater than 30 Mbph. What do I need to do to get Netflix in HD
