hi

after hours of trying to find the optimal settings for win vista i found that EVR is still the best option..
Overlay-like things, opengl, direct3d are dropped because of the aero. VMR's, haali, and EVR stays.
VMR7 windowed - ok, but cant display info on OSC with tab
VMR7 renderless - seek is bad: fast-playing frames till the seek position, OSC ok
VMR9 windowed - has OSC-problem
VMR9 renderless - has fullscreen lag, funny seeking comes once again, OSC ok
EVR (C/A) - the best so far, seek is ultra-fast, OSC info is working, but has fullscreen lag.
Haali would be perfect but it displays a green screen because of NVIDIA Purevideo doesnt like it. Didn't test the seeking speed though.

Let me explain the fullscreen lag - it happens ONLY when paused:

case 1: i switch IN fullscreen mode:
the video is resized instantly to fit fullscreen
(but ony window sized part is visible)
the window moves to position 0,0
kmplayer waits 2 seconds
then comes the fullscreen

case 2: i switch OUT fullscreen mode:
window moves to original position
kmplayer waits 2 seconds
video resized to fit in the window

Note that even though i was testing with a 60 fps HD 1280x720 mpeg2 video, this happens with 30mb-ish low resolution files.
Purevideo knocks out KMP transform filter so i cant use it to be able to display info on OSC with any renderer.

Please help me. I know it doesnt sound like a big problem but i just cant get used to it.
