Everytime I switch my camera to Video mode, I get the white wording that says "If maximum recoding time is displayed in yellow, the camera may shut down automatically do to rise in internal temperature -Move Record Size " Then shortly after it says "Err 70 An error prevented shooting. Turn the camera off and on again or re-install the battery." At this point the photo-video switch does nothing and the power on/off/lock switch does nothing. Only removing the battery will "restart" the camera. If I put the battery back in, while it's still in video mode, the camera never comes back on... if I put the battery back in in photo mode, it'll work as normal in photo mode, but as soon as I put the camera back in video mode, it does the exact same error, making video-mode non-accessible at all.
