Which video sites are currently supported por fanpop for embedding?

fanpop has to implement a widget from each video site (such as dailymotion) provided por that site in order to support video embedding. Video embedding is what allows you to watch a video on fanpop - none of the vídeos is stored on Fanpop's servers; instead the embedded link is like a window to the other site so that you can watch it on fanpop without going to the other site.

My pergunta is: what is the complete and current list of sites for which fanpop has implemented/enabled embedding?
