Hello,

I've been having troubles burning downloaded movies onto a DVD disc that will play in my DVD palyer. Most of my downloaded movies are in mpeg, avi, divx format. and I cannot find a free program that convert/shrink the file so it will burn properly onto a DVD disc. Any help would be greatly appreciated!!

If the video is already in MPEG format, there is no need to convert again.
What you should do is to use a DVD Burning software such as Nero to burn the videos.
