I want to know if it is possible to put a video on one side of a DS DVD and some .PDF files on the other. Any suggestions would be great. I have a video I want to be able to play in a DVD player and computer but I also want to have these .PDF files available for download & print on the disk.
You can certainly put PDF files on one side of a DVD10 (that's the double-sided type).. they do seem to exist.
Of course, you could also put those PDF files on the same side as the video. Keep in mind that, unlike CD, DVD is just DVD. Every DVD is a "data" DVD, it's just that a DVD-Video disc has certain files in certain places, to make it easy for a dedicated set top box to figure out. An extra directory full of PDF files (or anything else) doesn't cause a problem.
Read your manual about DVD-ROM content- this can be done on a single sided DVD. I.e. DVD playable content and computer content can and do reside next to each other in different folders. As The Joker once said, "it's all part of the plan..."
