Some download a video file only to learn about CODECs. Here's a link about codecs. http://www.moviecodec.com
my windows media player on my other computer xp pro is not working as it should when I play a video file I get a small picture surrounded by blackness it looks blurred but this could be due to its size I've tried right clicking the screen there is a thing full screen I clicked on but it made the whole monitor go black. I've tried system restore did'ent fix the problem. I had the same problem on media player 9. I dont know much about media but does anyone think I may need a new video card is this something to do with media player?
