How to change video codec?

I have download a DVD RIP movie ...its AVI ...i burned the movie using PowerISO into a DVD ...but ..when I try to play the movie on my DVD Player ...it says video codec not supported ...only sound comes out ...it doesnt have problem with other movies ...please help me ...

Your DVD player should have come with an install disk and the codec would have been installed with it. If that has been done, you can do a google search for "DVD Codec" and try to install another one. Select a codec specified for your operating system (XP, Win7, Vista etc).

If you're sure the above has been done, it is also possible that this might be a copyright issue or that the burner was set for Data files instead of a DVD movie at the time it was burned.
