I'm having a rather odd problem with iMovie HD. I've made myself a video that's about 1 minute 30 seconds in length. I want to export it to .WMV. I select Export, then Quicktime, then Expert Settings. I then click Share, and then under the Export options I select "Movie to Windows Media", and use the default settings. The movie exports ok, with one problem... it only exports about the first 22 seconds of the video. How do I get it such that it exports the entire video?
