well, im not sure what videos you are watching, but it could just be the videos format. Also, try using a different software to run the videos. But really, most likely if you are watching them from YouTube, they have thier own format(widescreen or fullscreen) so in the event that you may not know that it is widescreen, there would be nothing you can do about it.

o and justingh, how did that answer the question hahahahaha lol
