Guess what? I had bought a Canon 70D tutorial DVD and I set up the video shooting as the guy suggested. After I sat here wondering what to do and getting nowhere, it hit me–do the simplest thing. I re-set the camera to all default settings and voila, it shoots video like it’s supposed to. I can now use this camera’s great features and shoot video, what I really wanted to do with it.
Thanks for your help. So, default settings did it.
