Basically, you select Video DVD format on your burner. Add the video file, select output size disk (4.7 GB = 4.36-7 GB in real size, 8.5 GB = approx 7.7-8 GB). Once burn is selected & blank disk put inside burner tray, it should convert & burn.
If your burnt disk so far does not have a VIDEO_TS folder inside, then you must have accidentally burnt a data disk & not a video disk.
