Can't play a video

[effemmeffe]

I tried to play a video, but it won't start, I only get the audio and a window on top with the Now playing message.
Here the mediainfo of the video: http://pastebin.com/m747rsFd
Here the log: http://pastebin.com/TFGf1fNc

In the past I had no problems playing videos with higher resolution than this one.
