Some of you have commented that the post I create on Embedding Youtube videos in PowerPoint is still not working for you. So here’s what I will do: I will give you a link to create a screencast that you can send to me. I will be happy to look at the screencast and see if I can help you out. In the area where it asks for your name, please put your email address. Then, send me an email to let me know your name and email address so I can verify that you are real (yes, I hate spammers as much as you)
So if you are still having problems with embedding youtube in Powerpoint, click this link and send me a screencast.
