sorry adminstrator...for asking here these question, but i am trying more and finally fail.....

my vlc player give me error while playing wmv file..

"VLC does not support the audio or video format "MSS2"

any one know how to solve this problem plz help me ....thanks

These keywords should have been enough to find internet pages that deal with exactly this problem.
Anyway: you need the mss2 codec e.g. obtainable at Microsoft's support pages

Also, it seems to be necessary to Set Extras>Input&Codec>Use system codecs for WMV codecs
I do not know what your version says to the menu entries and I cannot test it.
