Help with DVD-lab pro

[Jack the Ripper]

I've been struggeling to add subtitles to a film I've finished on studio 9 and texts I wanted to make on Subtitle workshop.

At some point I read somewhere that it may not be possible and that the DVD-lab PRO would be a good answer for this.
I'm not interested in investing money in another authoring program, but I do have the trial version of it.
Now I'm stuck trying to learn a new program just because I didn't know how to add subtitles with the studio 9 and subtitles workshop.

My questions are:

1) Is there any other way you know for me to add subtitles in 3 different languages using only studio 9 and subtitle workshop?
2) If I do have to use the dvd-lab pro, I can't hear any audio's from the films I'm using. What's happening there? Is it because its a trial version? The restriction of formats there is quite uncomfortable and totaly new for me.

I'd appreciate the shortest most productive tips you could offer.

Thanks!!!
