Back when I wrote the post you're referring to, ATi drivers for Vista didn't 
have OpenGL support yet. That came with ATi Catalyst 7.01 (the January release).
So yes, now I could use the OpenGL video out driver.

I tested OpenGL output in January, but the video playback was rather slow, 
despite the CPU only being used up to ~75%. Now with the February driver 
release, it's even worse (maybe 5fps or so). There's a lot of tearing as well.

There's another reason why I don't use OpenGL: There seems to be an issue with 
fullscreen, or at least switching from fullscreen to window mode.

I start playback, video plays in a window. I hit 'F' for fullscreen, which works 
as expected. If I hit 'F' again, Mplayer switches back to a window, but doesn't 
restore the original size. Effectively it shows a maximized window, with the 
video completely stretched (no black bars).

Since DirectX is working again, this isn't a big deal for me, but some might be 
bothered by it.
