by default, choose full html for the 1st ligne, tq:
- Check “Convert Media tags” under Enabled filters.
- If other roles besides the system administrator need the ability to embed Media into node content, those roles should be checked in the “Roles” checklist
configure the CKEditor profile for Full HTML admin/config/content/ckeditor/edit/Full : add icone "embeded media"
Note (dec 2013 update) : the ckeditor libraries v4 bug with media. Take 3.6 with media - see http://drupal.org/node/1853550
