Hey everyone, I found a pretty simple workaround. I don't know that it will work on an iPad, but works fine on my computer and there's no affect on the video size and no need to download extra applications. It all functions normally.
1. Go to the Music library.
2. Select Playlists (located at top horizontal menu).
3. Create a new playlist.
4. Your new playlist should now display on the right side of the itunes window.
5. Now you can go into any of the other libraries and just drag and drop into the playlist.
6. Click the Done button when you're done adding episodes to the playlist.
Now that you have a playlist created, you can keep adding on to it - say you want to store all TV seasons under one playlist. To do that just :
1. Select your desired playlist.
2. Click on the Add To option located directly underneath the iTunes Store button (top right).
3. Now the playlist should appear on the right hand side of the iTunes window and follow steps 5 & 6 from above.
Hope this helps. Let me know if you have questions.
