Ok, I found a clip that exhibits this. It shows in the default movie player on the nexus and also the mx player app.
Can someone out there play this back and see if you notice it? I think it's pretty hard to miss, but would like some others' feedback. Watch the black parts of the video (especially the guy's hair on the left) and you'll see some really annoying blueish/light-blue blockiness in the black areas. This same video played back on my dinc doesn't show this.
I'm also curious if people with a Rezound can check this? That will probably be my next option if I return the Nexus.
Thanks in advance.
