[MPlayer-advusers] Weird slow decoding problems of DVDs on Mac OS X 10.3.9

[Ergzay]

I have gcc 3.3, ld cctools-525.obj~1, and make 3.79 all runnning on Mac  
OS X 10.3.9 on a 1.2 Ghz iBook G4.

1.2 Ghz G4 should be plenty to decode a DVD but for some strange reason  
I am getting frames dropped at a rate of several frames every second or  
so. Often more if its high action. If its still motion I still get  
frame dropping although not as much. I am not quite sure what is wrong.  
I'm not quite sure what info to supply, please tell me what other info  
I can supply if needed. (If I don't use -profile sub I've found I drop  
less frames but still drop some.) I did not have these problems in the  
past but it has been a long while since the last time I played a dvd  
using mplayer (several months).
