DVD Burning problem

I burned a dvd off the internet and it works on my computer buts it doesnt work on my dvd player??? how do i fix this???

You have to provide more information. Is the source movie avi, wmv, mov, mkv, etc? Are you converting the movie, if so, with what program? What burning program are you using? What operating system do you have? What are your computer specs? What make/model? What brand stand alone dvd player do you have? What brand of blank DVD? Do you know the manufacturer of your DVD burner?

A windfull from Whappo…but those are the info and spec we need to help you on this problem. The amount of help depends on how much info you can provide.
