I upgraded to 4.1.4 and now I have had nothing but trouble. At first, I lost the ability to access my SMB drive attached to Time Capsule - even though all other computers in the house did not. Then when I tried to use the Network Setup pane in Nito I got an error and a system crash. So I downloaded a fresh install to my USB thumbdrive and reinstalled everything. No change. I tried removing the external USB drive, no change. Then last night I reset my AppleTV to factory and started all over. Reinstalled 4.1.4 and now Nito network setup works, but it will not recognise my SMB drive, however it does the same USB external attached to the AppleTV. But now XBMC gets a blank screen when launched, even though it is apparently running fine as I hear the menu clicks. One problem after another. I am temped now to go back and reset my AppleTV to factory and use the older version of AppleTV OS and stick with something that at least lets me watch my movies! This has been the worse upgrade since I have been using ATV Flash almost two years ago.
