AVI to DVD burning

Hello everyone! I’m very new here. First post actually. I have downloaded avi. and mpg/mp4 movie files, but I cannot figure out how to burn the files to a dvd. Can someone help me?

What burning SW do you use? Does your standalone player support AVI playback?
Or are you wanting to convert AVI or mp4 to DVD?..

Usually legal movies come with advice on how to burn them on cd/dvd…
