[MPlayer-users] Error playing VC1 file on 32 bits host, but it works on 64bits

[Jean-Yves Avenard]

Hi...

I have experienced some errors trying to play a BD rip of I Am Legend
that contains a VC1 video stream..

This is using the default mplayer package of Ubuntu 8.10 , as well as
compiled from SVN trung (revision 28045 retrieved about an hour
ago)...

Both packages were compiled with the exact same options, with the same
development packages installed.

To play it on 32 bits platform, I have to expressly specify which
decode to use with:
-vc ffvc1

Any ideas what's wrong and why auto-detection fails to work here ?

Thank you
