same here :-( i get a black screen then it gos back to the tv even after removing the kodi folder and removing and reinstalling kodi
Happen to have one of these receivers laying around have not fired up in ages, it's the Opticum HD2400 version but I am sure they were exactly the same thing as the Mut@nt version bar the badge on the front... Fresh flashed with latest OpenATV 6.3 (dated 25/08) and installed Kodi, exactly the same results as the guys above report, black screen, after a short while reverts back to live TV, so not looking like anything image/ViX specific, ATV is doing the same...
