I know this has been posted several times, but the thread titles are inconsistent, so I apologize for being repetitive. Doesn't happen always. Seems to happen most often in the mornings after an overnight of standby mode. I'm not sure if this is due to the xbox getting an update, the TV app having some issue, because my hopper checks for updates and reboots every night, or sequence of xbox powering on devices, or....?
I've seen this issue posted in many places, for many setup combinations with different boxes and providers. My guess is it's an HDMI and/or app issue. Hard reboot fixes this, as does disabling standby in the power settings...but that's a sucky solution.
