I opened the video using windows media player but the video is not good quality because my cell phone camera is 2.0 megapixel. Can I use any other program to open that video so it can be of better quality? Or how can I edit it to make it better? I am running on windows vista. My cell phone is a samsung alias 2

Try to use Video Converter and convert the video to other formats with better quality. I think it helps you well. Free download website: http://www.total-converter.com/video-converter.html
