Since updating the software to add the star rating system i am noticing the optik pvr freeze up more to the point i have to reboot the whole box. Recently last couple times i don't rate a show , eventually it goes to the green menu where it says press okay to return to tv, i do that and nothing happens, do it again and then you hear the tv channels turning if pressing up or down for channel changes however it still is at that green screen until reboot. Not sure if its the software or the hardware but it did only start with the most recent update.
