I know I have to reburn the DVD. What I am looking for is a way to avoid any re-encoding of the video just to change the title in the menu.
As I said, in this case I can just recreate the DVD since I still have the movie in the DVR. But someday, I might not have the source and would hate to degrade the picture quality of an entire recording (from re-encoding) just to change the title in the menu.
The title is either in text form on the DVD somewhere or a “picture” of the text. So unless there is some proprietary encryption or CRC or ???, it should be simple for a program to change just the title once the DVD files are copied to a PC. My problem is I don’t know what program to use (if it exists).
