Why doesn't vimeo embed correctly??!

I’m at my wit’s end. Why does Youtube embed where it should here:

and why does Vimeo not do the same but extend the <td> next to it to a size where the vid itself is pushed out of the frame:

I just don’t get it, no defining a size for the “beschrcell” to the left of the clip helps reducing it, it just stays that way. The template for both posts is the same, so it HAS to have something to do with the Script of the embedded players. but WHAT?? and how can I prevent that from happening?

Any help is much appreciated, thanks!!
