I just purchased a Canon Rebel T2i, I have been trying (for days now) to record video, and every time I attempt to, the camera will stop recording at any time it pleases. The videos I have taken vary between only 3-20 seconds long, because it keeps stopping. I don't understand why this is. I have an 8GB card, if that helps. Please help! I have a 7 week old that I would love to be able to record! :)
