I've been having an issue in the past few days with Netflix. I've been watching the recent season of DEXTER in "SuperHD" but the picture quality has been all over the map. Unlike Amazon and VUDU which stream in full HD when you launch a title, Netflix takes some time to "warm up." At least with my Roku 2, Netflix starts out in low-res and after about 20-30 seconds switches over to HD. Well, these last few nights I've found that the image rarely looks like it gets to full 1080p. Picture quality may hold for a minute or two and then it sinks back to fuzzy, blurry low-res. I go to Amazon, no problem. I go to VUDU, no problem. My Roku box is hard wired and I have a fast connection. I do a speedtest over wireless and I'm getting over 20mbps. I've re-booted the Roku, no difference. I've re-booted the internet box, no difference. Anyone else having PQ issues with Netflix?
