My b2evolution Version: 3.3.2

I'm trying to embed a valid code for video from my video
host in a blog post using the HTML option, but I get this
error message. ( below )

I'm not sure what to do to "deactivate" this error message.
I already tried the "basic security setting".

* Illegal object markup found: </embed
* (Note: To get rid of the above validation warnings, you can
deactivate unwanted validation rules in your Group settings.)
* Invalid content.

Thanks,
Ron
