Since we have transitioned from using our macs to using Windows and Linux, we haven't had a solution for importing our movies from our camcorder. I looked today for an application that has the same functionality as iMovie for my linux laptop. Kino looks like it will do the job.
You can import your video via firewire into Kino. Kino will control a DV camcorder during the import. Then you can edit and export into various formats. It seems that Kino is faster at exporting to flv or mpeg4 than iMovie is.
The only problem that I had was when I initially tryed to import the video. I got an error message that stated: "raw1394 kernel module not loaded or failure to read/write /dev/raw1394" To fix this, I needed to give myself permsion to access /dev/raw1994
chmod 777 /dev/raw1394
