Help req'd for new boy

Greetings
I want to produce a film to go onto DVD to send to relatives. What I want on screen would be a menu which would then show one of, say, four different movies that I've cobbled together. So, not chapters of the same film, if you follow. How do I go about this, please? Obviously, at the end of editing it in iMovie, I can share with iDVD, but this sets up a new DVD - or am I getting confused? Do I save it to Desktop and then somehow ship each one in turn into iDVD? Also, if I want narration, is it simpler to record this with GarageBand and then add it to iMovie or iDVD? Questions Questions... GarageBand seems to offer a bit more flexibility when recording sound and I would prefer to use it for the purpose if it is feasible. If it makes sense to do it this way, how do I go about it, please. Final thought, I don't particularly want suggestions like 'Download XYZ prog.....', I' d just like to use iLife 06 which is installed on my iMac. Thanks Mitcherooney.

From iMovie export each video as a quicktime movie. Then fire up iDVD. Then you import each of the movie you created. You will have an item for each movie you import.

Thanks rman I'll give that a whirl after feeding dogs, doing the washing up and any other chores that my Significant Other has left me... I'll get back to you.... Cheers M
