okay, thats very interesting 4 me. just on this hard topic i´m exasperating…
the hardware ist also an dual G5 ppc 2,5 GHz with liquid cooling… fcp is running but no way with the old hdv codec, no realtime, no import, export, only native projects are functional.. but for older projects is this rubbish.. an never mac is not possible cause the apple xserver-raid on it have apple-like-special interface-cards in pci which are no longer available for intel-macs cause they have only pci-express interfaces 🙁
if you have some instruction for my problem, maybe per mail or her? that´s great!
