Normally you’d look for the embed code at the place where you find the video (MTV in this case). Not sure they offer embed codes for sharing. But if you find them you can usually get those to work in your posts and pages.
Ya I’ve embedded hundreds of soundcloud and youtube videos, but when using the normal embed code for datpiff, mtv, worldstarhiphop or any of the others it doesn’t work. That’s why I was wondering if there was a certain plugin that I need, or a certain way I need to reformat the embed link.
