Metadata Extraction Problems

I am new to Serviio. I have an extensive video library of Movies and TV Shows, and wanted to test Meta Data Extraction. Things don't work as described in the WIKI. I can't get any metadata defined for my library and would appreciate help.
File naming is supposed to drive this. I am providing some simple examples of what I have tried below..
..\Movies (This is one shared folder)
\Movies\Casablanca 1942.mp4 (This title is on www.themoviedb.org)
\Movies\Cinderella 1965.mp4 (This title is on www.themoviedb.org)
\Movies\Cinderella 1965.jpg (This is a DVD Cover image used as an experiment for Serviio)
..\TV Shows (This is one second shared folder)
\TV Shows\Hogan's Heros (This Series is in www.thetvdb.com)
\TV Shows\Hogan's Heros\S04E02 Klink_vs_the_Konculator.mp4 (A Test Episode. There are others in the directory)
So, then, in Serviio's metadata menu all defaults are selected. I choose under descriptive metadata "Online Metadata Sources". (I did this after the default returned no metadata.) and then SAVE and RESCAN VIDEO METADATA.
So, I was hoping...
1) It would Identify Casablanca and Cinderella as Movies
2) It would display appropriate thumbnails for the movies and provide a description as you can get online.
3) It Would Identify Hogan's Heros as a "Series", perhaps more description.
It did none of the above and I have experimented extensively. It did provide a generic icon for Casablanca and Cinderella, but these were not correct for those movies/years).
I am thinking of giving up. I do not know where this generated Metadata is stored, I figured, maybe I could edit it, but that would be time consuming given the size of mu library is actually in the thousands of files (Only experimenting at the moment)
Any suggestions?
