last week i bought a mac pro.. with the idea of video editing.. i cannot connect my panasonic pvgs 120 camera to this new computer.. i tried 2 different firewire cables.. called mac support.. no help!! when i go to imovie it does not recognize the camera.. here is the weird thing.. it worked 2-3 times already, but only by luck.. i know it is not the camera because i tried it on another mac and it worked perfectly fine!! another thing.. the firewire system profiler does not see the camera!!! what do i do!!! heeelp!!!
