How to put title

I have 2 dvd movies on my HD. I know how to burn this 2 movies in one dvd as well. But I don’t know how to creat title (name of the 2 movies) at the start of the disc when we play back. Normally when we playbak there is to browse to choose which movie we want to see. I want to know how to creat that browser scene in dvd. Anybody who knows please help me.
Thanks
