Would like to change Menu - My Dvd options

I would like info on how to change the Menu - My Dvd folder items before starting to convert to dvd.
Currently, it sets VSO as the background image, and title as “my dvd”.

I am making a video dvd as a present for mother’s day for my mom/mom in law, and would like my child’s current age picture to be the background, and the title to be his name and age.

I can do splitting chapters and setting the titles for chapters, I just need help locating these files/folders/options to change them.

Thanks in advance!
