Wondering if maybe just have some conflicting CEC commands from your other equipment interfering with the Roku.
Try performing a Factory Reset on the Ultra 4800. On the bottom of the unit, there is a Reset Button. Press and hold it in for 30+ seconds. (this will require you to go through the setup and activation again - just use the same email address you did before and everything will be restored back to your account). Will have to log back in to any subscriptions, but hopefully this will fix your current issue.
