Romain,

 

Please try your code in this example.

 

 

If it works for you, please download the latest build.

 

There are two types of yourtube embed code.

 

1. Old embed code

<object width="480" height="390"><param name="movie" value="

 

2. New embed code

<iframe title="YouTube video player" width="480" height="390" src="http://www.youtube.com/embed/TU_4WDtfCis" frameborder="0" allowfullscreen></iframe>

 

The latest build of Cute Editor should work for both situations.

 

Keep me posted
