I suspect you haven't gotten a lot of replies because most folks stick with either iOS or Android. There's quiet a few different video formats, and not having an iPad, I have no idea what format they use (or even how you go about importing ... can you just use a USB port?).
You might want to check out the program Handbrake, a well known and free video converter. I imagine you probably need to download the video to a PC (or Mac), do a conversion, and then upload to your iPad.
