Setup: 2011 Macmini quad core with Mountain Lion EyeTV 3.5.6 2 x Elgato Diversity Tuners LG Plasma TV connected via HDMI After having the above setup working nicely for over a year, about two months ago I updated to Mountain Lion and have been plagued my EyeTV application crashing. I was hoping the latest update to update to EyeTV 3.5.6 would have fixed the issue but to no avail. EyeTV seems to usually crash when the HDMI connection is activated (ie. when the TV is turned on at the start of the day). As I've found some recordings to have stopped at that point. Also when watching EyeTV recently, I changed the TV input to switch to the TV's inbuilt antenna and when I changed back to the input for the mac mini, EyeTV had crashed again. So the catalyst that causes the crash definitely seems to be associated with the activation of the TV's HDMI. Any idea's how I can fix this issue?
