I can't watch more than 2-3 hours of TV and the Co-Star will lock up. This happens with live TV and Netflix. The screen will stay on with the image frozen. It seems to be related to my using the Co-Star and/or the remote. I say this because I ran two tests. One with Netflix and one with Live TV. I turned it all on and walked away for many hours. When I came back, it was still working for both tests. When it's frozen, I can use the remote to turn up/down the volume on the TV and the Co-Star will power off when I hit the remote's power button. I have to unplug the Co-Star and plug it back in and it works again. It literally happens every time I use the Co-Star. I have the latest update.
