My Mini seems to be getting worse as time goes on. Hulu is the biggest problem: more often then not the audio will play but the video is static. Rebooting the Mini usually fixes it. Sometimes I have to Reboot the host Roamio too. A couple of times I've had to reinstall the Hulu app on the Roamio. Now periodically recordings won't play either: the sound is fine but the video is black. The same recordings play fine on the Roamio and are fine on the Mini after a reboot. Suggestions? Other than frequent reboots?
