Guys : can you try the video with a smaller / lower resolution video?
It seems that some of you have videos (that will indeed play in mplayer default) but whenplaying outside of mplayer (even being mplayer) we cannot use mplayer fullspeed, then you probably not going to get image in too high resolution videos.

Also the rotated kernel can BE a real issue, because the video didn't play when rotated AT all.

We will do some test... but if this is the case then there will be no way but flashing again : /
