Hi guys! After shooting dSLRs for years, I am now thinking of getting my first camcorder. My MBP has about 160GB left after giving 100GB to bootcamp, letting iTunes and iPhoto09 swallow they part and now I worry about storage for editing, processing and exporting video. I have been thinking of getting one of those Western Digital FireWire800 drives. But is it possible to set up iMovie09 to use the external drive 100%? So in this way I can avoid having temp files and those massive AIC files on my MBP hard drive?
