I have an iPhone4S. I have checked "Manually manage music and videos" on the Summary tab, viewed in iTunes.
I have added 2 videos that I recorded into my iTunes Library (as "TV Shows"). I then drag those two from the Library and drop them onto the iPhone device. They do show up there (under the "TV Shows" in the left sidebar), but not when I click the "TV Shows" at the top of the center window (which I expect since I'm not using Sync to manage things).
However, when I disconnect the iPhone, I cannot find those 2 TV Shows to play them. I used to be able to find them in the "Video" app. In fact, that's where I find such videos on my iPad. But now I only see the option to PURCHASE movies, videos, etc. in the Video app (or the iTunes app) on my iPhone.
How can I access the videos on my iPhone to play them?
(I can, BTW, play them from the phone, in iTunes when it's docked to my computer, so I know the movies are playable videos. But, obviously, that's not the way I want to view videos on an iPhone!!)
FWIW, it's not that the "TV Shows" category is special in this way. I also drag videos classified as "Movies" into my Library and then from there onto my iPhone. And these also show up in the iTunes view (when viewed from my computer) but I cannot access them via the Video app on the iPhone. All I see are Videos that I can purchase from the Store.
