Hi All,

I am just new to this forum.

Hope someone will help me in fixing the issue i face with my mencoder.

My platform is Centos 5.

When i am converting a wmv file to flv i get the following error.I am using the latest available mplayer version.

Though the flv file gets created, its video is moving very fastly.The audio plays perfectly.
