You have a "Refused to display document because display forbidden by X-Frame-Options." in javascript console. Some sites explicitly refuse to be displayed in iframes.
I was able to get some iframes to embed on my notebook server by modifying the url to use https:
from IPython.display import VimeoVideo
v = VimeoVideo(id='53051817', width=800, height=600)
print v.src
>>> 'http://player.vimeo.com/video/53051817'
v.src = v.src.replace('http','https')
v
IPython now supports IFrame directly:
from IPython.display import IFrame
IFrame('http://stackoverflow.org', width=700, height=350)
