well, making some tests it looks like it is a simple task,
I inserted the {youtube}VideoID{/youtube} en the specific place on the article i want to show the different videos, and that got the job done.
lets say:
Text article, blablalblablabla
{youtube}FirstVideo{/youtube}
More article text, blablabla...
{youtube}SecondVideo{/youtube}
End of article.
Thanks.
