I made some debugging about this issue. It is due to the action names in the .desktop file not corresponding to the DBus actions of totem, plus the mute action isn't among the one implemented in totem.
I made a patch to fix the names and add the mute action to totem. This is my first contribution to Ubuntu so please tell me if there's something wrong.
