I got a question. I am catch some streams (Movies) with the ending .mp4 and when the Media catcher is done he makes a new ending with .flv.

orginal stream name is


after the Media catcher is done


When I change the ending to mp4 or avi the movie is playable but i can not see how long the movie is. And some players have problems. Is there a way to fix the file without convert it?

Best Regards
