mplayer plays ogg video problem

Intrepid 8.10:

When I play this video:
http://videos.ubuntu.com/qa/assigning-packages-to-bugs.ogg

BUG: I use the seek bar to seek the middle of the video, then the audio starts over from the top.
But the video output works correctly.

it could be a gstreamer bug, and totem couldn't even play it.
