I decided to provide the alternative approach, I think it's easier as you don't have to move the title menu to the root menu. Look in the attachment for more details. You can use this as a reference for your future DVD made from dvd recorder.

Look at how I change the button command. R[2] is used to contain the chapter number and LinkTailPGC jumps to the post command, which is then jump to VMG Title 1. In the pre-commands of the movie PGC, you'll see that R[2] is used to check against a chapter number and jump to the appropriate program.

In the precommands of the title menu, I made it so that button 1 is highlighted at first. But after you play the video and decide to press Menu or Title menu, the button corresponding to the last played chapter is highlighted.

Just copy everything from my project over to yours and modify your project to look exactly like mine, or you can just copy the movie over to my project.
