ipad home sharing partial library

I have iTunes 11.0.4.4 running on Windows 8. Home Sharing is enabled, and I can see the library from my iPad (iOS 5.1.1, all latest updates installed).

When I go to my iPad, tap "Videos," and then tap "Shared," I get only a portion of my video library from the source computer. Oddly, I get everything except the "last" season of my TV shows.

If I have 4 season of a show, only the first 3 show up. This is consistent across four shows -- 4 seasons, I only get three, 20 seasons, i only get 19, 7 seasons, i only get 6.

I've rebuilt the library.itl file using the .xml rebuild instructions, and the library appears to be fine. Similarly, when I plug the iPad in to the computer and physically transfer the files, there doesn't seem to be a problem.

Help?
