Also depending on your idea of what you're doing with the disk. If your video is already fit onto a CD you should be able to simply make a VCD (Video CD) which will play on nearly any DVD player. By converting it to DVD video (MPG4) you may actually lose quality. I would more say burn your video to a CD-R then if your CD burning software has it, create a VCD. This shouldn't take more than an hour and you already have all you would need. No need for DVD disk or converting to other file formats.
