Watched K-19 today. It was the true story about the first Russian Ballistic Missile submarine. The picture was crystal clear without any stuttering or pixelation. I've watched a number of the NTEK movie offers and they all have worked flawlessly on my Samsung TV via Verizon FIOS. I have also watched some 4K on Youtube and Amazon Prime. Although they also performed well without problem. The picture quality on Amazon was inferior to NTEK product.
