Use the link I posted above. If your VIDEO_TS folder is ready-to-go, then using DVDImager is the next-to-last step to getting a video DVD.
DVDImager will apparently make an ISO image in UDF format out of your VIDEO_TS folder, then it's just a matter of using Disk Utility to burn the ISO to a disk (even though you can't manually specify UDF format, Disk Utility respects the format of the disk image and will burn in the same format as the image).
