Try using the latest version of SDL. I believe it's 1.2.7.

It might still be a too slow processor. Neither MPlayer nor VideoLAN 
Client have been heavily optimized for the PPC processor, so they 
require much more processor power than Apple DVD Player. So it just 
might be that...

Another possibility is that you need to increase the buffer size. The 
easiest way to do this is adding this line to ~/.mplayer/config:

cache		= 16384	# use 8Mb input cache by default

double=yes		# use double-buffering (recommended for xv with
			# SUB/OSD usage)

These lines might also be useful:

vo=sdl			# To specify default video driver (see -vo help for
			# list)

ao=sdl			# To specify default audio driver (see -ao help for
			# list)

fs=no			# Enlarges movie window to your desktop's size.
			# Used by drivers: all

# vm=no			# Tries to change to a different videomode
			# Used by drivers: dga2, x11, sdl

# bpp=0			# Force changing display depth.
			# Valid settings are: 0, 15, 16, 24, 32
			# may need 'vm=yes' too.
			# Used by drivers: fbdev, dga2, svga, vesa

zoom=yes		# Enable software scaling (powerful CPU needed)
			# Used by drivers: svga, x11, vesa

framedrop 	= yes	# drop frames, when not in sync (slow CPU, videocard,
			# etc)
