TV is strongly dependent on the itunes connection. The iphoto connection works not because the photos are in the pictures folder, but because iTunes was updated to facilitate the connection of personal photos. Now, it would be nice if Apple would add a lot of capabilities to

TV, so that many of the (many) wishes about what

TV could/should do could be granted, but whether they'll choose to ever get to any particular wish is always up in the air.
Here's another way to get closer to your wish.
When it comes organizing video so that they aren't in the one long "movies" list, you need to tag them as TV shows. With TV show tags, you have fairly good capabilities to organize content as you desire (though they still have to be managed by iTunes (and thus exported out of iMovie for this purpose).
Because, like you, I didn't want home moves mixed with (non home) movies, this is exactly what I did:
1. I tag all of my home movies as a TV Show (Get Info, Video tab, Video Kind- TV Show).
2. In the "Show" field, I put in Home Movie (for all home movies, NOT using distinct names in this field)
3. In the "Season" field, I put in the 4-digit year in which the home movie was shot (for example, 2008)
4. In the "Episode ID" field, I put in a 4-digit month/day (example: 0614 for June 14). If I don't know the exact date, I use best estimate.
5. In the "Episode Number" field, I put in an incremental episode number based upon when this video was shot vs. others shot in the same year. For example, if this is the 5th home movie I shot in 2008, the Episode Number will be 5).
6. In the "Info" tab, "Name" field, I punch in the name as I'd like it to be shown in

TV. Unlike the "Show" field above, this is where individualized home movie names work best.
7. For "Artist" I use "Home Movies" (all of them are tagged this way- no distinct artist names).
8. Lastly, in the "Artwork" tab, I put in a nice tall image often culled from (iPhoto) photos taken at the same event in which the home movie was shot. If there are no photos available, I open the home movie in Quicktime, then screen grab it using the grab option in the Preview application. I always try to grab images that are about 2ce as tall as they are wide, much like movie posters. As such, when grabbing from QuickTime, I am cropping content from the sides so that I end up with an image that is taller than it is wide. To my eyes, these tend to look better in the

TV equivalent of cover flow.
With them tagged as described above, they'll show up as a single line item (Home Movies) in TV Shows on

TV. Clicking into that item will show them grouped by episode ID number, most recent to oldest home movie, with the names you entered in #6 as on-screen video descriptors). And if you tagged them as above (using 4-digit year for Season field), your movies will be split out as "seasons" by year, giving you a nice chronological organization to your home movies.
Over time your iMovie raw files will get dramatically larger and larger, always putting pressure on your readily-available hard drive storage situation. So rendering them down to H.264 will make it possible to have an "always available" copy of your home movies in relatively modest hard drive space. Then, you can move a relatively huge iMovie file offline (as in off your main accessible storage) when the day comes that you have so much iMovie video stored and not much room for more (readily available) hard drive storage.
I have nearly 2 terabytes of home movies in iMovie format (they do add up quickly). But they take only about 50gb as H.264,

TV-ready videos available to iTunes.
Until Apple makes some meaningful adaptations to iTunes for better video tagging & organizing purposes, the above is the best way I've found to get fairly close to at least some of your objectives.
