Youtube Playlists

Hi,
The Youtube embed codes don't seem to work on the Youtube pages any more however just pasting the link to the video (rather then the <iframe> embed code) works fine. Neither the embed code or the link work when embedding playlists though. Is this something that should work or can anybody suggest a workaround for when you want to use more than one youtube video on a single page?
Thanks,
Karl

change http to https in the iframe code.
