Problem with the QWidget::winId() method

You need to force OpenGL or DirectX output. Try adding a -vo gl2 (or -vo directx) option to mplayer.

I have already tryed with those two options without success :
* No sound and no video when forcing output to OpenGL
* No video when forving output to DirectX

It is strange because ... I'm not sure of that ... but the same application played video with success under Windows2000, but as I said, I'm not sure of that point.
