i'am using latest version of OpenATV v4.2 (older version seems affected too),
my problem is, if i watch movies (mkv, avi, mp4) then i press stop, media player cannot cannot back to main menu (using EMC).
so, i had to reboot my STB before i can use it

(it's not always freezing but so often, very annoying)
is there any fix for this?
