mozilla mplayer plugin does not play video

["H.S." <hs.samix@gmail.com>]

Hello,

If I click on a video link, mozilla mplayer plugin shows that it is
downloading the file but doesn't really play anything. After the
download is complete, it tells as much and then it either doesn't do
anything or just prints "Stopped" message in the mplayer window (which
is within the browser).

Could someone help in solving this problem?

I have these on my machine running 2.6.15 kernel and Debian Etch:
