Loop using Nero Vision Express 3?

My work requires me to study a set of video clips by viewing them a number of times. I was looking for a feature in Nero which would allow me to -

1 ) Loop the clips infintely
2) Atleast go to the main menu page after each clip.

For my requirement its more convenient to do it while authoring the DVD rather than using AB repeat feature on a DVD player.

How do I use Nero to do that for me ?

Any help is appreciated.
Thanks in Advance.
