Anybody been having trouble with playback errors on their Roku 3? I watch a lot of NHL games through NHL Game Center Live and lately, I'll be watching a game and the picture drops off and a window pops up that says PLAYBACK ERROR and proceeds to tell you that you may have to unplug your device and start over and if it continues to contact Roku. It's happened numerous times in the last week and I've unplugged it nearly as many times but it still happens. Never had any trouble with at all until the last week or so. And I don't really know if it does this on other channels, since the NHL one is what I usually watch on it.
