About infoEnable & nowplayingEnable

Hi,
After reading the music api guide, i didn't found how to do to get the varaible infoEnable, to get more info shown int the videoplayer. The fact is that i wish to add infos relating the videos published in my site. When i set the variable infoEnable to "1", where do i put the informations to be grabbed by the api and be published with the video, like in this example: http://fr.news.yahoo.com/2/20081024/video/...ir-acb3f14.html
sorry for my bad english, cause i cabn write better in ma native language wich is french.

Thanks alot for your help!
