I have had that problem before, I improved the freezing by booting my modem, router, and box. I have magicjack on my router, and that seemed to be one source of the problem. I have to unplug the power on the magic jack every couple of days. That seemed to solve most of my problems. But, when you get a freeze on a movie, try pausing, go to the bathroom, get a soda, a snack, popcorn, or put the cat out. Anything to eat up a few minutes. I was doing this before the discovery of the magic jack problem and this stopped the freezing until the last of the movie. Could not solve the issue the last 20 minutes of the movie for some reason. Maybe I was too impatient wanting to see the end.
