There never was VDPAU hardware that did not do full hardware 
decoding for H264.

Does VA-API support 1080p60? That is what G520 supports.
Is there de-interlacing? I consider that the most important 
VDPAU feature.

I decoded four (or five?) 1080 video simultaneously with pre-520 
hardware without problems.

Then please do not send mails that make the impression that it 
is the MPlayer developer's fault that VDPAU was heavily pushed 
(=patches were sent) by Nvidia while nobody cares to send 
patches for VA-API (and XVBA).

Or in other words: Please send your request to the recipients 
who actually can change something.
