Im a newb at burning DVD movies, help please

[A is 4 PiMp]

I've a few movies on my PC, I didnt get them by putting in a movie and taking it off the disc:cool: . Ive been using Roxio DVD Builder for burning a few movies, but now it suddenly wont work with the ones I want to burn. These movies are .avi files. I just want to be able to put them on a 4.7 GB DVD and be able to play it on any tv or dvd player. Ive just decided to post this because all of the programs that ive been using dont work, I have no clue why. Maybe someone can help me out, thanks
