Ok, it really seems as the decoder needs to take care of the directdraw 
sourfaces, and the dlls can't be used with current MPlayer.
Therefore I think it would be the best to create a vo similar to xvmc. 
Unfortunatelly, we are lacking documentation/sample code for this.
Looks like you have to use closedsource players or switch to linux, when
you want to use the hardware decoding features of your card.
