I created a template with the element slideshow and blog. I selected in the element blog one category. After this, I add this template to the page. It runs ... but: I would like to show the entries in the post timeline layout. If I select this type of layout, all blog entries are shown.
On the other hand, I created one template for a blog and I selected a lot of categories, except one. This is the page, what I set for the standard blog, too. But with our without this selection: All blogs-categories are shown there.
