uninstall all the codec that you have, and use either CCCP or k
lite
and try not to install too many player also, because it can also
have conflict also
try opening the file with MPC player, vlc is known to have problem,
it is a over rated player, even gom player is better than vlc
if the video is corrupted, then you can't even open the file at
all, next time, just use g spot to test the video
