Text content of video post affecting the layout of the home page grid

Hi,
I like the way posts are sorted in the home page (in my case not a static page, but a list of recent posts). However, it just happened to me that I added a new video post, and the grid looked very different: all recent posts were aligned in a column on the left (leaving a lot of space on the right).

After playing around with this new video post, I realised when this happens (though not why). It’s a bit complicated to explain… This issue happens when the last word that is shown in the short summary of the video is a link.
It happens with video posts, not with standard posts (I haven’t tried any other format). For example, consider the following text:

“””

<!–more–>

123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 (link)
“””

In my home page this will show a new post, which contains a video and a summary that is cut at some point because it’s too long. If the cutting point is the link, then the problem with the grid layout happens. Does it make sense?

In fact, the length of the short summary changes depending on the number of links, as if the characters in the link were actually characters shown in that summary.

Finally: Why is the short summary made with the first paragraphs of the blog post, and not with the excerpt of the post?

Thanks a lot!

Pablo
