If your personal Home Movies are encoded to a different format using Handbrake and the Apple TV2 preset. when imported they should appear under Home Videos
If you want them to appear in a different section then you can change the Media Kind under Preferences, Options from Home Video to Movie
Alternatively you could set this value before sending it to itunes using a product like Subler where you can set the medi kind and the other hidden tag of Explicit or Clean if you wish.
Then save it and from within Subler File > Send to iTunes
It will copy it into itunes in the right place
remember it is illegal to rip commercial DVDs it is only allowed for personal Home Videos that you put on a dvd
I was having the same problem today with a m4v file. After a bit of searching around I found that manually putting it in iTunes' "Automatically Add to iTunes" folder did the trick. All of my earlier attempts to drag the movie into iTunes showed up as well (in the Home Movies category). I deleted the extra copies and added my own meta data.

" just copy the movie to the folder 'iTunes Media/Automatically Add to iTunes' located in the iTunes Library folder, usually in the /Users/username/Music folder but you may have it in other location even in an external hard drive. "
