Hi, I have about 6 sequences of my wedding video.

1.the wedding
2. the reception
3. the reception decorations first of day
4. the outtakes
5. the words of wisdom

I want to make the dvd with a custom menu with a clip of video behind and rolling videos of each of these sequences.

I have fcp suite 7

what do I do with the sequences first. I have marked my chapters in each sequence. do I have to put in/out on each? etc...

Simplest way: Export each sequence as a QuickTime movie. Open DVD Studio Pro and import the sequences. From there you can build your menus. when you burn the DVD, the program will compress the video and audio for you. For more info there are plenty of resources to learn how to make DVDs.
