The file contains two different video streams, one coded with 8BPS and 
the other one with SVQ3.
MPlayer does not support this.
Is it a trailer you downloaded somewhere?
Usually you have a still image (or few frames) coded with an old codec, 
and then the real clip codec with a good compression codec.
Why do they do this? I don't know. Mov format supports a lot of 
strange, unusual features nobody cares about that have no pratical 
purpose except causing troubles to players that doen't implement them. 
Looks like trailer codecs are exploring all of that.

Selected video codec is 8BPS (Planar RGB).
As someone else pointed out, currently MPlayer can't decode it.

Audio is QDM2, you need qt binary codecs to play it.

Audio is configured, you qt binary setup works ok.

Video codec not found. That's ok, 8BPS decoder is not implemented 
natively, and not decoded with binary codecs.

I'm implementing a native 8BPS codec, it will take a few days.
Anyway, probably won't be able to play it anyway without some other 
patch.

Do you have an url for the file? If it's not available on the net and 
not too big, can you upload it to MPlayer ftp?

BTW, Faad is an audio decoder, and has nothing to do with your problem.
