I'm not quite sure what you're describing. You also may have posted in the wrong forum - this forum is for PowerDirector 15, which came out in 2016, so you shouldn't have just bought it. Maybe this link is the right forum for your question?

If this is the right forum, I'll start by saying that PowerDirector doesn't "convert" anything to or from PDS files. PD saves its projects as .PDS files (which stands for PowerDirector Script), and each project file contains a list of all the media clips you've added along with all of the instructions on how to process them according to your edits.
When you Produce a video, PD runs the project's script which then converts your timeline clips into whatever format you've selected, like MP4. There's no way it can "produce" any media clips to a PDS file, and it doesn't convert them into a PDS file before, during or after it produces your video.
I think it would help if you can post a screenshot or a screen recording of what's happening, and why you think PD isn't producing to MP4 the way you saw the trial version do.
