Sony sr80 to imovie 08 using streamclip+quicktime component? Is this possible?

With MPEG streamclip + the quicktime component, I was able to get my clips onto an OLD version of imovie by converting them all to DV. But this isn't working now that I have the new imovie 08. What should I do? Should I convert it into something else??? I don't know very much about this but I didn't ever have any trouble editing my little movies until I got ilife08. I still have access to the old imovie, since i stored it on an external drive, but the subtitles things in the new imovie are way better and I want to use them. The clips are all on my computer, but they just won't go into the new imovie. Help!!!
