i would suggest too that you check the size of the pictures you are using. I use Sony Vegas Pro, but I down size and convert any jpg files to twice the resolution of video I am working with (i.e. NTSC 4:3 is 720×480 so the pic is 1440×960) and save as a png. png is a lossless or less lossy format than jpg and the files size is a lot smaller. If you are dealing with a lot of pictures, you are loading up the memory really fast and going to the hard drive swap file too quickly.
