Roku 2 unit. Enjoying latest HD Star Trek. Stops in the first 5 mintues, freezes, Roku automatically reboots itself. Highly annoying. This has happened on my original ROKU as well. Is it just me, or are there updates being activated even when the box is being used? I can think of no other reason for the box to do a full restart on it's own. If so, why isn't the code written to update ONLY when the box is idle??
