Slackware :: Mplayer Not Initializing In 12.2?

I have downloaded mplayer svn slackbuild script for slackware 12.2 and converted into tgz package and installed it on my slackware 12.2 system. I was using it with slackware 12.2 early and it worked fine. i formated my hard disk to give slackware 13 a try. and later when i installed slackware 12.2 and installed mplayer it is not opening i mean not initializing when i click mplayer icon from the multemedia menu or if i click a videofile and tell it to open with mplayer both ways its not working i tried reinstalling mplayer
but still not working.
