Similar to AQ_OC, what I do is plug my iPad into my PC. Assuming for a second you use Windows (though I don't see why something similar shouldn't happen on the Mac), your iPad will show up as a portable device (like an external hard drive) so you can navigate to the iPad using Windows Explorer, again, like any other drive on your PC. Your videos should show up in one of the folders in the DCIM folder. you can then use Windows Explorer to copy it over to a local drive on your PC.
