All, I'm running into issues with program guide refreshes. When a refresh is underway, the Shield is virtually unusable - not just Plex, but Live Channels, HD HomeRun app, everything - until the refresh completes. I read that guide refreshes occur during scheduled tasks or upon a restart if the guide is more than 18 hours old. The latter appears to be my issue and I don't see a way to stop it from happening. Any help would be most appreciated.
I'm trying to replace my cable boxes with an HD HomeRun / Plex / Shields on each TV, but this is really causing major problems and is making it hard to convince my family to make the switch. If the media guide update is making the the TV not available when people want to watch TV, then what good is having the Plex DVR? I might as well just switch back to cable boxes.
