I have a MacBook Pro and Toast 9 with the plug in for blu-ray. I am trying to download HD video from a canon camera. When i download the movie to iMovie and drag it to Toast it doesn't burn in 16:9. Does anyone know what format I should save it in before dragging it to Toast. Or if you know a way to get my HD video to toast a better way to burn to blu-ray I could really use the help.
