I updated to the SiliconDust HD Homerun 4K network tuner about 2 months ago. Everything was working fine until about 3 weeks ago. I noticed that the few programs I had scheduled for recording did not record. This continues to be a problem. When the scheduled program is supposed to be recorded, the guide indicates that it is being recorded. However I don't see an entry in the list of recently recorded shows. I checked the directory where programming is stored and there are empty directories for the missing records. So apparently the recording tried to start but was unable to capture anything.
Yesterday I was able to watch live TV. Last night and this morning live TV is not available either. When I select "watch" there is a brief pause and then MC just returns to the previous Guide screen.
I am able to watch live TV just fine with the HDHomerun application that is running on my Mac Mini in a different room.
