Television Show Thumbnails

I searched around on the forum but couldn't find what I am looking for, so if anyone knows where this has already been answered, please direct me to the correct thread.
If not, here goes. I am wondering what the filename should be for my Television thumbnails. Currently none of my thumbnails are displaying and instead, the image that is displaying on my media machines (including the Seriio MediaBrowser webapp) are auto generated by Serviio. My thumbs that I have in the folders are ignored.
My folder structure is like this...
[tv]
[Television Series 1]
poster.jpg
fanart.jpg
banner.jpg
tvshow.nfo
[Season 1]
Episode S01E01.mp4
Episode S01E01-thumb.jpg
Episode S01E01.nfo
Episode S01E02.mp4
Episode S01E02-thumb.jpg
Episode S01E02.nfo
Episode S01E03.mp4
Episode S01E03-thumb.jpg
Episode S01E03.nfo
[Season 2]
Episode S02E01.mp4
Episode S02E01-thumb.jpg
Episode S02E01.nfo
Episode S02E02.mp4
Episode S02E02-thumb.jpg
Episode S02E02.nfo
Episode S02E03.mp4
Episode S02E03-thumb.jpg
Episode S02E03.nfo
etc. etc.
Everything works except the "-thumb.jpg" filenames. I do not have any files with the "-thumb.jpg" under my MOVIES structure, just the tv. Therefore, all the movies are working with their posters, etc.
I even tried thumbnails named with a "-poster.jpg" ending, and it seemed Serviio TRIED to pick those up. Unfortunately something would get confused and all of the images displayed were the same thing. Even thoiugh I had a different "-poster.jpg" for each episode, all of the episodes in that season/folder would display with the same image on the Media Browsers (ie PS3, XBOX, etc). It was strange.
In my console, I have both "Generate Thumbnails For Local Videos" and "Look For Local DVD Cover Image Or Poster" checked. Should I change something there? Any help would be greatly appreciated.
Thanks
