How to copy 2 films onto 1 dvd

First use full backup option to load the first title. then switch to re-author and drag over only the main title. Then switch back to full backup and bring in the next title, swith back to re-author and select the main title of that movie. Then set your compression and push backup.

It will go a head and and put both title on the same DVD and when you insert the DVD it will start playing the first title automatically. The only way to get to the second title is by stepping/searching up through the chapters to the start of the second title.
