HD video - fast playback problem

[cumaniok]

I've tried this, but it didn't help much, I still got a frame updated in one
or two seconds for playback rate x16. 
My file has high resolution: 1920x1080, with h264 codec. I'm developing my
application in C#, using .NET bindings, may this be the reason for bad
performance when playing with high rate?
