I have one menu with chapters which, for a full day church wedding, looks something like this

Prep
Arrivals
Ceremony (full length)
Celebrations at the church
Celebrations at the reception venue
Bride and Groom photo/video shoot
Speeches (full length)
First Dance
Evening/Dancing

Ceremony and speeches are in real time with live audio - the other chapters are set to client choice music - served me well for 5 years :)

Hey Pete

Guys Prep
Girls Prep
Arrivals
Ceremony (the Service part)
Register signing
Congratulations
Photoshoot (just my video shoot set to music on Stedicam)

Video Guestbook during pre-dinner drinks
Bridal Entry
Guest Tables
Speeches

Now, On DVD 1 they get a Play All link and then
Preparation

Ceremony

On DVD2 sub items are

Speeches

That's my standard layout but with a long ceremony I sometimes break the ceremony into 3 parts so they don't get bored
