I had similar problems on my Ubuntu 10.04 box. I could not get MPlayer (or gnome-mplayer & gecko-mediaplayer) to play any movie.
I found the error when trying to start mplayer in a terminal. I'd get: mplayer: relocation error: mplayer: symbol codec_wav_tags, version LIBAVFORMAT_52 not defined in file libavformat.so.52 with link time reference or mplayer: relocation error: mplayer: symbol rgb24toyv12, version LIBSWSCALE_0 not defined in file libswscale.so.0 with link time reference. Clearing all foreign packages installed by ppas or other sources (guilty packages were libavformat52 and libswscale0) then reinstalling mplayer solved the problem. A good way to spot these is to open Synaptic and select "Origin" as filter. There you can see all the packages installed from remote sources.
