All my TV Shows are in m4v and contain metadata, so it pulls all the metadata from the file. I store all my episodes for each show in one folder (A folder for The Simpsons and another folder for Family Guy) and mediaplayer doesn’t show the Season and Episode numbers in the info in the bottom left corner. This means once at the metadata has been loaded I can’t tell what episode is from what series.
I think you should add this info to the TV Show layout.
