I doubt your problem has anything to do with DVD drive speed. The problem is decoding of the MPEG2 stream. MacOS uses the ATI chip hardware IDCT and Motion Compensation engine, we can't in linux since ATI doesn't provide infos/specs about it. So we have to do 100% software decoding for which your CPU isn't fast enough (well, it _might_ be if someone really understood how to hand optimize the algorithm, but I'm not sure :). On G4 machines, we have some altivec optimisations that make it doable, but that isn't the case on G3s. Ben.
