Ulead DVD Workshop 2 - cannot join clips

It seems simple, but I couldn´t manage it so far - maybe I´ve got some misconception concerning the software - would you be so kind to help me out.

I´ve imported two mpegs into the so called "content window". Now I want these two to be treated as one single clip. It was only possible for me to create and join chapters within these clips, but they are always displaying as two seperate films in the finished DVD.

Any help would be highly appreciated. Thanks.

 

Thank you very much for your quick reply.
I think Womble MPEG VCR 3.14 is a very capable tool, but is it possible
that this elaborate Ulead DVD Workshop 2 cannot do joining, especially because it is a matter of rightclick menue to do this in Uleads beginner tool Moviefactory ?
Moreover I cannot cut at every frame in DVD Workdhop, although there is the same timecounter as in moviefactory, in which frameaccurate cutting is possible. So I would use Moviefactory, but it´s encoder is bad (aliasing effects).
Maybe you or somneone knows about this.

 

I don't remember exactly -- but, it's like hit the SHIFT or the ALT key and click on the clips. Hope it works.
