I had the same problem.

This skin uses script.skin.helper.widgets to get recently added, in progress and such widgets.

If you could set smart playlists as widgets your problem would be solved. 

I've sent some PR to include "path" as a filter and edit my widgets links to include this filter. It works like a charm.

Hope it helps you 

Thanks. It's working, but it doesn't shows movie posters. 

How have tou defined widgets? As posters, thumb? Might me a cache problem. 

Defined as posters.

And if i go the other way:
Adding D:\Movies\Subfolder to library, the widget shows cropped posters with filename text under the cropped poster.
The widget recent movies works. The posters are full sized.
