Ok got 1 system running osx 10.5.5 but if i use medialink to watch video on ps3 it keeps hanging and waiting on data as in audio drops out or video will pause. I ve tried different media streaming software. Ive taken router out of the equation (direct connect). Changed network card for a different one (different chiptype). I can copy the file to the ps3 in a quick time but if i try to play im sure its either lossing packets or osx isnt keeping the traffic going so the ps3 runs out of data. Any other options to play with in osx other than whats in prefs panel. Or any suggestions
