I need to lower the file size of an .avi file without deteriorating it too badly... so that it will fit into 4.7GB, it's around 15GB... DivX lowers the size enough, but I don't know how to properly burn it into a DVD. All tutorials I have found seem to be a great amount of hassle. If anyone knows of a simple way to do this... including or excluding Divx, please let me know.
