mibox + xbmc = wrong aspect ratio?


Apr 29, 2014
Hi all,
I use xbmc on xiaomibox, but unfortunately if I want to watch a show always the aspect ratio is wrong. In the video setting I've already change the "4:3 stretch to 16:9", but nothing change.
If I watch a show (stream) and want to change the settings in the video settings (normal, 16:9, 14:9 etc.) the screen switch to full screen. Looks like the screen stretch always to 4:3 and the black top and bottom just overlay the movie, not scale them.
Have you any Idea wat can I do?
