Thanks Michael! Yes, menus. However, I've simply used one of their transitions ("blur"). Would you be able to easily explain how to add a sound effect to that -- or is it only when I create my own transitions that I can include audio?
But I know in DVDSP built in transitions don't have audio, to use audio to make an in-between video that has audio and video but if you are using template menus you really cannot but your own blur transitions. If you want to have custom menus with more advanced menus you need to build them yourself outside of the app. Other apps made provide more options.
