Any way to just add menu?

Hi people,
Ive been trying to put some Xvid files onto dvd for standalone and run into the usual audio sync probs frequently when using all in one encoding/authoring progs but have had great results with VSO avi to dvd.
I can batch a whole series of files overnight and the individual .vob files are great.
I run into problems when I try import them into an authoring program to get a menu. They seem to come out jumpy/jerky or I loose the good audio sync.
Ive been trying nerovision7 and uleadMF5.
Is there a program that will leave the vob files untouched and create a simple menu?

Thanks for any help

p.s. the audiodub and tmpeng process looks far too complicated and time consuming for my purposes :doh:
