when playing movie in project window it cuts part of the video screen
I purchased Call Recorder for Skype to record my girls violin lesson over skype with their teacher in Bermuda. Now I need to cut certain parts of the video so we can play it during practice .. I don’t want to play the entire video. I had the Record Video set to "Two Track (Advanced)". I imported the recorded .mov file into iMovie. Then I skimmed the video and selected the part that I am interested in and dragged it to the project window. Now when I play the movie in the event browser, it plays the movie as I would like to side by side. However when I play the segment that I selected in the project window, it cuts 1/2 of each window which is not what I want as I would like to able to play this clip showing both the teacher and the student. What do I need to do???? Help!!!!! Thanks!
