Did you place an MP4 with H264 encoding (the best choice)? You chose File > Place, right? Did you preview it in the Media panel? Did you preview it in the SWF Preview or EPUB Interactivity Preview? Did you choose File > Export > PDF (Interactivity)?
Finally, what PDF reader are you viewing the PDF in. Make sure you using Adobe Reader or Acrobat.
Thank you for your answer to help me. Yes, I have done all of those things that you mentioned. For the viewing of the PDF, I just used the viewer that is with the Indesign when you open it to preview it. I am at a loss.....
Steve! You did it! thank you. Adobe reader was the answer
