This may help, may not.  When I was playing with this a year or so ago,
I found a HD test video on the internet somewhere.  I'm pretty sure it
was 1080p.  I set smplayer to play and repeat the video and then I
watched the CPU and temps on the video card.  I would try each setting
and see how much CPU load there was and watched the temps on the video
card.  I figure if the card temps are warmer, it is giving the card a
work out instead of my CPU. 

I ended up using "gl (fast)" for mine but this may not work at all for
your system.  This may give you a way to test the settings and sort of
know if the right hardware is doing its job or not. 

Here is two links if you want to try my weird way of doing this:

I use downloadhelper to grab those then play them locally.  Both of
those are available in 1080p tho.  Should warm up something.  ;-)
