Does anyone have any experience using Production Suite (FCP HD, DVD Studio Pro, Motion) on a Powerbook they'd like to share with me (esp. Motion performance)? I'm going to buy a PB 1.5gHz, 128 Video Ram with a 5400rpm 80 gig, but will settle for an ibook superdrive if a PB can't play hardball with Pro Suite. Any help would be great! Cheers
