You could just take requests for burning the raw data files to a Data DVD and let the rabble convert them for themselves. I don't mean that to sound heartless, I just know enough about video and DVD mastering to tell you that VOB files are somewhat difficult to wrangle... I'm certain I could transcode them for myself but I don't know how helpful I could be for others as I am using professional video editing applications to do it which are not cheap or easy to master. If you own a Mac, I would suggest MPEG Streamclip as a starting point.
