Actually the old PPC Macs aren't really that bad. It's just that lots of the time-critical functions in both XviD and libavcodec (MPlayer's decoding library for both ASP and H.264/AVC) is written in heavily optimized assembly code... but not for PPC - for x86 with MMX/SSE. Which means that when used on a PPC architecture, it has to use the plain C code paths, which in some cases can be orders of magnitude slower.
