>1. For vcd creation, are there any transition style options?
5.0 does not have VCD transitions.
5.1 has transitions (but at lower quality)
Version 5.1, beta out now, see here for more details and download:

>2. Any way to have more than one music file play, sequentially, during
>a VCD slide show, instead of having the same one play over and over?
Yes. Just add more than one track to a slide show using the Sequencer.
>3. What happened to the "Customize" tab option, as visible in the
>tutorial on the web site, under the VIDEO/CD tab?
It does not exist in VideoCD mode. It is in PC slideshow mode and in the
Professional Edition. Also it has been renamed to "Dialogs"
