Ok, using OSS audio output makes mplayer to play this file flawlessly. But
turning back to alsa makes the problem re-appear. Which version of alsa are
you using?

That's weird. I have almost the same output and it plays slowly. If I
disable sound using option "-ac null" then it plays perfectly. So it's not a
video codec problem, but more an audio codec problem.
Here is my output :

Hey Anthony,

I've played the video in Totem and in Mplayer and both plays
the video exactly the same.

Maybe the output of mplayer will help you:

mplayer

Totem video player handle it correctly. I'm using latest revision of
mplayer
:
MPlayer SVN-r29484-4.3.3 (C) 2000-2009 MPlayer Team

My OS information : Ubuntu 9.04 x64.

Cheers
