Streaming video is sent in a specific size and format, it is done that way to be compatable with a wide range of screen sizes, including the smaller dumb phone sizes.
If you create your own video, you can choose the correct size for your screen.
If there is a particular video you want in full size, use a service like Blueapple.mobi to download and save the video. Use a video converison program to reformat it to the correct size and save that to your media card.
