Embed video different sizes Blog/Blog List

Hello SI Team

I embed a video here:

http://finalbug.net/blog/entry/404-in-depth-3d-titles-fcpx-10-2-part-1-of-3

Using the Standard EB Embed video tool.
I set the dimensions to 800 times 450.

This works fine in the Blog list mode:

http://finalbug.net/blog

But has a different size here:

http://finalbug.net/blog/entry/404-in-depth-3d-titles-fcpx-10-2-part-1-of-3

Please advise. This is driving me nuts

thanks

Paul
