I have a laptop, Toshiba, pretty new, 2.8 ghz, 512 ram etc. with firewire and a DVX100a. I imported a whole buncha footage, stored it on my LaCie drive and edited it in Adobe Premiere. Now all was going fine, but now when I play it back or go to record it to tape or export it in any fashion, it's all jittery and hangs up and it sounds like my hard drive is cranking overtime just to keep up, it's so bad I can't evne playback in the workspace to see what I'm editing. I am at the end of my ropes here fellas, any help would be greatly appreciated.
