The only hope would be a Cyberstorm with a CybervisionPPC as other gfx cards don't have enouph ZIII bandwidth, even when using Mediator or Prometheus. A PPC native OS would also be required and probably an optimized player. Only one I know is DV player. Oh and a SCSI HD to offload the CPU load.
Only ones with such a set up are probably some very few AmigaOS4 betatesters running DV player, maybe someone will post about it here:)
