Printing widescreen PowerPoint (2004) to PDF

I have been using Keynote for a while and have gotten spoiled by the fact that I can always export to PDF and the document is in the correct format.

So I had to use Powerpoint and I created the presentation in a 16:9 / widescreen / landscape type of format. When I went to print to PDF all I could do is create/use a 4:3 page size. As a result I had to scale the slides way down to fit on the "page."

Is there anyway to print/export to PDF such that I can either set a custom PDF page size or have PowerPoint page size used correctly when rendering into PDF?

Thanks
