Thumbnail Display (in Mezzmo & Samsung TVs)

[mcutugno]

Up until a couple of weeks ago, the thumbnails displayed in each folder were always of the folder.jpg file in the same directory as the file. Suddenly, this is no longer the case. After a certain date the thumbnails are now captures from a part of the file (see attached screenshot).

While the newer thumbnails are preferable to me, I would like to understand why the behavior suddenly changed. The date seems to coincide with the last release of Mezzmo, so not sure if any updates pertaining to thumbnails were made there. Is there a way I can go back and make all of my thumbnails look like this? I would like my library to be consistent.

Thanks.
