Quicktime Trailers for PPC problems

[Victor Ng]

I'm trying to get MPlayer installed on the PPC version of Ubuntu, but
I'm not having much luck.  I've never tried installing MPlayer from
source before - so I may be doing something entirely stupid, but I
don't _think_ I am.  

The build instructions I'm using are the ones at:

I'm configuring and compiling doing the usual:

 ./configure --enable-gui ;make clean; make; sudo make install

MPG video and audio work fine - I can still watch the dancing monkey
boy with no problem.  :)

However- I'm able to play Quicktime Trailers and _see_ the
video stream, but I don't seem to have the audio codec to support the
trailer.

The error I'm getting seems to be popular on Google:

"Requested audio codec family [qdmc] (afm=qtaudio) not available"

But I'm unable to find a solution to this problem.  Does anyone know
if this is a PowerPC specific problem or if it's just something I've
misconfigured?
