OK - I have a folder on a local drive for Television shows.
Inside that folder, i have other subfolders for each show . . .“Seinfeld”, “Eastbound and Down”, etc.
The problem is, I cannot get those TV show name folder to display a thumbnail. It’s wierd cause i got their subfolders to display thumbnails . .(“Season 1”, “Season 2”, etc.) but not the show name folders themselves.
If a folder is named “Seinfeld”, I am dropping a jpg in that folder named “Seinfeld.jpg”.
In case others reach here searching for a similar problem and the above solution does not work, check if the folder.jpg or <thumbnail_name>.jpg is a regular uncompressed or compressed RGB JPEG format. Folder thumbnails that are saved in progressive JPEG format are not handled by the WDTV.
