softhddevice + nouveau vdpau?

Yes, absolutely. Don't get me wrong -- I don't feel like anyone is obligated in any way. Devs owe users nothing, and users shouldn't expect anything from devs. It's just nice when devs put the greater good ahead of their own personal needs so all users have something more complete & robust. I know several devs in various areas who do this all the time and I know I'm not the only one who appreciates their efforts.

Let's just hope one of those nouveau devs decides his 1080i looks a lot better with good deinterlacing.
