Hi, need help with 2 questions creating a DVD using DVD Architect Studio 3.0

1) I want to have a lead in into the main menu (a short clip), but when I click the option to "insert introduction media" and apply it to the clip, when it runs I hear the audio, but the video doesn't play - all I see is the picture for the Main Menu.

2) How do I add a music file to play during the Main Menu?

Many thanks in advance!!!!
