"Some UltraFlix 4K clips showed acceptable video quality although not to the 4K WOW level. Other (perhaps too many) UltraFlix 4K clips showed unacceptable judder and video frame sync problems."
Only amazing to a long. The unbiased reviewer unfortunately saw otherwise and was clearly disappointed in the video quality of the UF material. What more the material is garbage so UF has two huge problems.
It's OK to agree with others when the facts are there. The quality of of the video demos on the website are poor. I'm sure everything on your NP1 has a WOW factor of 11 on a scale from 1 to 10. The reality is, the website demos don't look very good.
