i'm not sure
i tend to install from rpm's as there is a massive amount of cool stuff for mandrake 9.1
i have mplayer (probably the best thus far), xine and aviplayer
i've had vlc as well before and none of them have clashed or caused each other problems
but i never had much luck with ogle
vlc was the easiest to sort out
it needs a few dep to be added
a52dec, libjpeg, libdvdread, libdvdcss, xml2, and one or two others
vlc was the first media player i got to work
it's all at the
http://www.videolan.org site
not an answer to your question i'm afraid but i hope it helps
