Solved Screen flicking while opening an MP4 file

Hello,
actually i'm new to vista.. i have used n xp and win7 earlier.. jus now have installed vista home premium in my system(core 2 duo, 2.7GHz, 3GB RAM, 358MB graphics). i have a small problem after getting the new os.. i can play the usual audio/video files.. but when ever i jus click, or try to open a mp4 file, the screen starts to flicker and its like total refresh(opens all the minimised program).. this flicking happens for a while then it stops when i close the mp4 video file..
can any1 help on this prob..

Thank you..

Hello Dinesh and welcome to the forums

Remove any 3rd party codecs you have installed, then install Shark007's codec pack:

Shark007.net - Windows Vista Codec Package

This should clear up any issues you're having

Respected,
Thank you so much for your response.. but the codec which you specified did not solve my problem.. any ways your idea sparked my bulb.. so i just tried installing k-lite mega codec in my system.. that solved my problem now.. thanks anyways..
