I would like to link an youtube video on one of my blog post using the embedded code that
youtube provided. So I added in my post html view this code:
<iframe width="640" height="360" src="http://www.youtube.com/embed/mIhqjRWZ77Y" frameborder="0" allowfullscreen></iframe>
Before to publish the post I tested it, with the wordpress preview option. Some browser not works well.
This is the scenario:
1) Using the last version of the Internet Explorer browser the post with the video works fine.
2) Using the last version of the Google Chrome browser I have to reload the html page two times before to view
exactly the embedded video. After that the page works fine but when I load for the first time the page I don't see the video.
3) Using the last version of the Safari and the Firefox browser I have to reload two times the html page before to view the embedded video and
after I have a problem viewing the video. The message is that the format video is not supported.
Could you please help me to solve the problem. Which is the correct way to use the embedded code starting from youtube website ?
How can I debug the issue ?
