How do I do this for my DVDs I've ripped to my computer? For instance, I have 30 Rock Season 1, 2 and 3. When I go to look at it on my iPhone, the thumbnails in my "Video" tab are just episode thumbnails, but I'd love to have the season poster as the thumbnail instead of the episode thumbnails. BUT, when I tap the show in my video tab, and go to the list of episodes, there I want it to have thumbnails for the episodes, obviously. Isn't this how it's done? How do you give album art to seasons correctly?
