Ok - this has been bugging me quite a while, through several iterations of IOS and iTunes - and I've got to get this straightened out.
Have Home Sharing turned on. I can access just fine with both my iPhone and iPad. Movies display as expected, Podcasts display as expected. HOWEVER, TV shows are a complete mess. While I have everything organized by show/season, and defined appropriately within iTunes, what I get on my iPad and iPhone are about 5 of the TV shows and seasons repeated over and over. For example, I have "TV Show 1, Season 1". It shows as the first item on the list, possibly 2-3 other TV shows display, then "TV Show 1, Season 1" displays again. And when you click on it, it is definitely that show/season, repeated over and over and over. Several tv shows may show up in between, sometimes the same show/season is repeated one after another.
Now - to complicate things - I also have an Apple TV using the same Home Share. The TV shows display there correctly (although the order is not alpha, and not quite "most recently accessed". I'm not quite sure what drives the order here).
So - why is there a problem? And what do I do to fix it so I can correctly stream my TV Shows to my iPad via Home Sharing (and see ALL of the TV shows, etc)
This is what has worked for me. (And it shows that Apple has inconsistent implementations for sorting/presentation of TV shows across iTunes, the Remote App, Sharing on the ATV and Sharing on the iPad.)
Set these items in the "Get Info" dialog's tabs:
Video : Show - set for all episodes of a show to the same value.
This is sufficient for iTunes to group the episodes.
Info : Artist - set for all episodes to same value used in Video : Show
This is required for the iPad to group the episodes.
Info : Track Number - in correct sequence for each episode
I don't know if this is necessary. But it is where I started so I've got them all set.
Video : Episode Number - in correct sequence for each episode
This works for iTunes to display episodes in the correct sequence.
Info : Name - (optional) The episode's title. (This defaults to the file name imported.)
Video : Episode ID - set to same value as Video : Episode Number for each episode
With this field left blank the iPad sorts/presents the episodes alphabetically based on Info : Name
This is a rather ridiculous requirement of redundant data entry. And it clearly shows that no one at Apple is tasked to ensure that listing iTunes video content operates consistently across all the platforms which can present/display a common data set.
