My grandfather has a combined VCR/DVD player and loves to watch movies. But he's over 80 years old, and struggles with grasping technology. Therefore, navigating a DVD menu is a very difficult for him. And making instructions for DVD navigation is also hard, since GUI of the DVD menu is so very different from one DVD to the next.
Therefore, I want to make a copy of his DVD's, which only contain the movie, with one audio track and one subtitle. An idea might be to have the subtitle embedded into the video, if it's possible. But in any case, I want it so that he can just put the DVD in the player, and the movie will start up automatically with correct sound and subtitle. Is this at all possible?
I attempted this with DVD Shrink, and was able to remove everything but the movie, one sound track and one subtitle. And the DVD ran perfectly on my computer afterwards. But when testing it on his DVD player, I got an error message. So I suspect the DVD didn't comply with the DVD standard in some way. Is it legal (according to the DVD standard) to have a DVD without any menu?
