I've had my Roku since Christmas and I've had trouble with Netflix for a while now. When I"m watching a movie or show, sometime during the show, the screen goes blank. My TV senses the drop out in video and shows 720p (if the show was in 720p or it shows 480p). My TV will sometimes flash a PC type video setting, such as 1024x768 or higher. Occasionally, after a few seconds, the video will return. I know the Roku is still streaming since the movie comes back later in time than when the video went off. Most of the time, the video never comes back. I have to pull the power from the Roku and restart it. I've not noticed it on other channels like Pub D Hub, but I don't watch other channels as much as I do the Roku. I've tried changing the display settings from 1080p (my TV can play it back) to 720p, and lower, but no change. I thought maybe the roku is getting hot some I'm trying some different locations. So far, no change.
