I tried to embed this youtube embed code.

<iframe width="560" height="315" src="https://www.youtube.com/embed/33mRiPJzzEM" frameborder="0" allowfullscreen></iframe>

I get the message that Powerpoint 2010 cannot insert this video. Verify that the embed code is correct. Not sure what to do here as this is what was the embed code for this youtube. Suggestions??

I have done others and they have worked fine.

Thank you, Rita
