A dvd authoring and burning question

I am new to converting movies and burning them to dvd.I want to know how I
can make video_ts.bup , video_ts.ifo , video_vob etc. files into one so that
then when I have a movie that is made up of two parts I am then able to just
have two menus on my dvd , so then when I put my dvd of which I burn into
my player its just the simple case of choosing either part 1 or 2 of the
movie I would want to watch instead of a bunch of small movie files to
choose from.Can you tell me of a program thats easy and simple to use so
that I am able to do this with.And if possible being able to put more than
one movie onto a dvd with a menu to pick what one you would like to watch.

NeroVisonExpress the DVD Authoring program will allow as most Authoring
programs will.
Basically you just import your first video mpeg file or AVI, do the chapters
and then import your second movie file and away you go...practise without
burning to disk use HD instead.

 

I am a newbie, too. I don't know the answer to the first question (and I'm
not really sure what the question is).
But, the second question, about putting more than one movie onto a dvd with
a menu, is possible, and common. I know Nero Ultra 6 does that. I've done
it several times. I assume other DVD authoring software does the same.
