I have a HDHR 4-tuner device for OTA local TV, and a TVE tuner. Today I searched for a program that should be in the EPG next week Sunday, but couldn't find it. Then when browsing the guide, I noticed that the EPG for just the HDHR tuner was only available until Tuesday 7/14. I think I forced an update the tuner by clicking some icon that looked like a spinning circle beside the tuner (not really sure what that icon is for, because hovering it doesn't provide any help).
Why did I have to manually force an EPG update?
