I have some .m4v videos (I believe this is mp4 format?). In iTunes (v10.5.0) on my PC (Windows 7 - 64 bit), I did a 'add file to library' and they appear under TV shows under library.
Then I did a sync with my iPad. They do not seem to appear in my iPad (iPad 2, now running iOS 5). The rest of the sync seems to go fine (i.e. recent songs are added to iPad, apps are all fine). There is no error or warning message. Either I'm failing to see them in the iPad (I looked under TV shows and some other places, where should I look?), or they weren't really pushed to the iPad.
Perhaps the format is not supported or some other problem? Like I said, no warning or error. Finally, I should mention that in iTunes under "Dave's iPad", they appear under TV Shows.
How can I see my .mp4 files on the iPad?
