I have just moved to MAC from windows and I am having a problem importing an AVI file that I created on the PC in Movie Maker to Imovie. When played on the PC it retains its correct 16:9 aspect ratio. When I copy it to my Macbook Pro it plays in 4:3 ratio in both Quicktime and when imported into Imovie. I have created both an DV and DV widescreen project to import it into but it makes no difference. Why is MAC not recognising the aspect ratio. I have imported some clips directly from my panasonic GV400 camcorder and it keeps the aspect ratio. I do not want to reimport the media from tape as I have already edited and added music to the clips.

I am running tiger with Imovie 6.0.3. Any advice for a Mac Numpty.
