i will forward this to the chief developer of the project, Steve
'robux4' Lhomme from Paris, as he is owning an iBook and might be able
to help you here.

The problem is that VLC does not support Realvideo ( RV9 / RV10 / codec
ID : V_REAL/RV40 ), as Real Networks Corporation never released a
working decoder under the GPL or L-GPL license, and the VLC developers
will follow the GPL to the letter, forbidding to link to closed DLLs (
unless they are part of the OS itself ). There is a mplayer compilation
for MacOSX existing also, but AFAIK it will also not play MKV's with RV9
content ( it can do that on Linux and Windows ) because the only
available decoder DLL is only for little Endian machines, and thus
unusable on Mac's .
So, for the time being, i am sorry to tell you that MKVs with RV9
content can not be played on Mac OSX. I heard that the free Helix player
from Real Networks is available in a compilation for Mac's, but it also
cant play RV9/10, only old RV8 ( strange thinking from Real Network IMO
:-( ), and until there is no decoder library for RV9 for big Endian
machines, we have no chance to get this working.
Sorry i dont have any better news for you, lets hope somebody will
reverse engineer RV9/10 one day and add a free decoder to FFMPEG /
libavcodec ;-) ...
