Great this site & Forum! We have one problem since the change the chain of engraving of our Master's Live performance - Video / choreographic Ballet - with our MACBOOK pro 2012 2,6Ghz I7. We work on the STUDIO 3 and DVD STUDIO PRO to engrave(burn) the Final Master's, and reading on DVD Pioneer V7300 player Usually we made it with our TOUR(MAC POWER) PRO INTEL XEON QUAD CORE on 2008 A processor: Intel Xeon ( quadri-cÅ“urs ) 2,8 GHz and its driver: 16x doubles coat(layer) (1 or 2 times): IMPECCABLE/PERFECT for the reading and the use with DVD Pioneer V7300 to player! With our MACBOOK pro 2012 2,6Ghz I7 and its driver HL-DT-ST DVDRW GS31N: the Sound jumps as well as the video, and even sometimes impossible for the DVD Player to recognize the DVD! ( This macbook allows us to re-configure the Master's degree directly on the stage according to the dancers and the interpreters and to engrave(burn) it for exploitation!) Config Encoding: the video DVD in a definition of 720X576, MPEG 2 SD VBR a pass, Debit(Flow) 4,0 Mbps - Debit(Flow) max 7,0 Mbps - AC3 from a file .mov PAL 720x576, 16 bit 2 channels 48 000Hzt Somebody could help me to solve this problem, or to share its experience(experiment) with this material(equipment)! Thank you and All best for the end and new year!
