May be the video is broken? I have played some home made DVDs (weddings
etc.) in which I cannot seek. Mplayer gives me negative number as
remaining time and is coming back to 00:00:00 (time elapsed) from time
to time, while the video is running smoothly. 
So can you play normally this video and seek in it?
