Use pdfmarks with PowerPoint 2007

I would like to use pdfmarks to create a TOC with a PowerPoint 2007 presentation on a PC (Windows 7). I have Acrobat Standard 9.0 installed (along with its Distiller). I don't want to use slide titles to create the bookmarks (that works fine doesn't give my TOC hierarchy). Here's what I've tried and the results:

1. Putting the pdfmark code for my TOC bookmarks in a .EPS file. Can't insert it as a picture--PowerPoint throws an "error occurred while importing this file," as does Word for that matter). Apparently inserting .EPS files is outlawed since Office 2007. Tried the workaround at "I can no longer insert EPS graphics into PowerPoint" but either I did it wrong or it no longer works (PowerPoint gave "error inserting file").
2. Putting the pdfmark code into the prologue.ps and the epilogue.ps, enabling PowerPoint > Acrobat menu > Preferences > Advanced Settings > Advanced: Use Prologue.ps and Epilogue.ps. Then:
   • Print using the Adobe PDF printer. My TOC bookmarks show up and work fine (yay!), but the internal link cross references within the generated PDF file do not. They are blue and underlined, but not live. URLs in the PDF are live. Discovered on the web that this is as expected: supposedly the Acrobat PDF printer "flattens" everything like on a piece of paper and internal links don't work. True? (This approach invokes the Distiller as expected and the Distiller log looks fine.)
   • PowerPoint > Acrobat menu > Create PDF. This creates bookmarks using slide titles and also internal links depending on whether those options are enabled in the Preferences Settings tab as expected, but seems to ignore my prologue.ps and epilogue.ps files. That is, I get the slide titles bookmarks (if Preferences Settings: Create Bookmarks is enabled but not my own bookmarks from the prologue.ps or epilogue.ps file, and if Preferences Settings: Create Bookmarks is disabled I get no bookmarks). Does the Use Prologue.ps and Epilogue.ps option still work with Create PDF?
   • PowerPoint > File > Save As: Options: there are no options related to bookmarks, links, or pro/epilogue.ps files. Same results as Create PDF.

So--is there anyway to generate a PDF from PowerPoint 2007 that will enable me to create my own bookmarks and keep the internal links live? 

Thank you!
