Quick question about this: Does custom episode art need to be the same size as episode art automatically pulled from the TVDB? Or can it be larger (i.e. the size of season art)?
For actual TV shows, the differentiation obviously makes sense and works, since it prevents the episode thumbnail from totally occluding the season boxart. But for sports, this isn't really relevant since season art isn't a thing. Using the normal episode thumbnail size leads to a lot of wasted screen real estate, when there is no season art to worry about covering up.
