so sorry, we cannot see Youtube Videos in China. There is only a white screen. That is why I opened a Vimeo Account some Weeks ago. Easy to handle and no Problems. Click on the link which is shown under my Name and you can reach Vimeo.
You can place it on MCM as easy as Youtube Videos. There is another, new Button next to the "Youtube Button". The Number of your Video will be shown after uploading (in my newest case it was : 4391694), copy and procced as usual.
with greetings from Beijing!
