Your message, while fairly wordy, really says very little that is helpful. Where did you get this file? Did you encode it yourself? What did you use to encode? What was the original format? What is the brand and model of your DVD player?
http://www.dvdrhelp.com has some guides that might be useful, but based on your message, it seems to me that either you downloaded and burned the video without doing anything to it or it was given to you. My best guess, and it's only a guess, is that your problem is being caused by the resolution of the video clip being incorrect for DVD.
