When I open the new Video app, select a source computer, and select tv shows, I am seeing TONS of duplicates of american dad, each with the same listing. Also, other shows like Daria don't appear at all. What's wrong?
Just to rule out some possibilities, make sure every season is correctly labeled.
Go to iTunes and pick a show, Select All and then do a Command + I (info) and make sure they all have share the same info (checking the blue box will ensure they do).
I added the ", Season x" thing on the info screen and no change. They all are grouped properly in the video app, and each duplicate group brings up the same thing. It's very odd.
