Shockwave Flash object in Word2007 to Acrobat 9 Pro PDF video

Shockwave Flash object in Word2007 only converting to Image in PDF using Acrobat9 Pro:-

I set the Shockwave Flash object to embed: True & the video is located locally, so why isn't Acrobat 9 Pro converting the word video to pdf video.

I've tried:
- using 'Acrobat' section on Word ribbon to convert
- saving Word file to Acrobat using word's 'save as' command
- using Adobe printer within Word
- opening the Word file from within Acrobat

I've just reskimmed the Word 'advanced' & 'saving' options & I can't see any extra checks to make.

Thanks for this,
