Mac OS X 10.3.2 SDL and mplayer


I am using SDL on Mac OS X 10.3.2 (Panther), and am having some trouble playing
movie files in fullscreen mode through SDL, using mplayer. Whenever I try to
play a movie file in full screen mode using mplayer, mplayer flickers through
the frames, and stutters through the audio. This problem had occured when using
SDL 1.2.6, but someone had made a patch for SDL 1.2.6 which corrected mplayer’ss
fullscreen flickering. Is there such a patch for SDL 1.2.7? Where does the
problem lie, with mplayer or SDL?
