Hello all, i purchased a mac pro early 2008 with the 8800 video card and the raid card with 4 gig of ram. I use disk 1 in jbod and have the standard 500 gig apple hardrive there for my system and the 3 other disks are in raid 5 and i get about 160MB/s read spead from that array. If i know go to this page : http://www.usa.canon.com/app/html/See_The_Difference/ and get some full HD demo material from there , for instance the watchmaker demo, and i play that from my raid 5, i still don't get a perfect picture instead when the camera moves from left to right or in any direction , the picture starts to stutter , it does not stop playing it just is not smood. The reason i spend all my money on this set up , is to be able to playback full hd material without any problems, and i cant seem to get it to work. Is there anybody here who can help me fix this or explaine to me whats going on that i still dont get the fluid picture i expected ? Thank you in advance. Data.
