How do I make a dvd?

Hi, I have nero 7 and a dvd burner on my computer but I have no idea how to make a dvd. Any help would be MUCH appreciated. Thanks.

Video, pictures, movie or data?

Video. The files are MPEGs.

I was able to get it to work by making SVCDs, but the movie “blinks” every few seconds and it’s gets all pixal blurry.
