Ok, I applied your patch and added volume setting support. Also dvd subtitles
_should_ work (I added VFCAPS_SPU) but I can't really check it (no dvd drive):

It was a big hack, in short I added in mplayer.c another "audio decoding" for
hw decoding. It only take a packet and send it as is to the audio device. But
as I write before it never work good. I think the card need a near perfect
interlaving. I will try to continue this, but I think we must first plan a good common
thing for all hw audio decoder.
But now I'll try to add osd support :)
