I have embedded a video into a pdf, but the recipient can not get the video to play without flash player. Is there a workaround to not require flash?

We have a marketing deck in which we would like to include a video. I have got the video embedded, but I was required to download flash. The video will not play when the PDF is opened in a browser. Only recipients that are opening in acrobat, and have flash player installed are able to view. I want this to be simple for people to open and watch the video. If it is difficult to do, they won't take the time and will likely result in lost clients. Is there a workaround?
