Hi again!
Thanks for all the kind help I feel blessed for getting help here!

Umm heres another of my problems

when pushing spacebar in windvd/MPC..
*functions as Pause* the audio switches from 5.1 Vocals to center, then to pushed again its on the rear..pushed again its in the fronts..Thats VERY annoying and inaccurate sound. How to fix this? Then sometimes i get WHITE NOISE!! (push again repeat above cycle)
Thats very very bad when at high volumes !! not acceptabl!!

SPacbar should just pause video (when playing)
Pushing it again will cause cycle forward in frames (WINDVD)
Pushing it again will resume playback (MPC)

Seems pretty normal. Can't comment if cycles through audio or menu when video is not playing though. I use PowerDVD. Maybe you have keys setup for audio channel mapping?
