[MPlayer-users] using the -sb option

I am trying to use the seek to byte location (-sb)
to restart a video (mp4) at the point I stopped it.

mplayer -alang en -ao alsa:noblock -noconsolecontrols -really-quiet 
-quiet -fs -monitoraspect 16:9 -cache 64000 -sb 2057102 SharkTale.mp4

The video does not sync up and restart correctly. It gets all blocky and 
remains blocky.

I am using rc2 on Amd64 at this time.

Am I doing something wrong? below is what starts printing on the screen. 
The sharktale trailer video plays fine if played all the way through.

Thanks,

Jerry
