Would the type of compression used affect the rate of iMovie importing? 
  I have tried MPEG-4 Motion JPEG A and B and DV/DVCPRO before I started 
using the RAID.  The first movie I did with the RAID was in DV/DVCPRO 
format.  It is a much bigger file than the MPEG-4, but it imported 
rather quickly.
