What's so great about it? How are you using it on your Apple TV? The addons didn't seem particularly noteworthy. I've never used Kodi before so I'm sure I'm just missing the appeal/favorable attributes, etc.
I have used Kodi for years to stream content I ripped from my discs (e.g. a few hundred HD-DVDs that I ripped after the format died) on HTPCs and other devices. On the Apple TV I use MrMC, Kodi's close relative.
What's great about Kodi from my perspective:
- Very high-quality video playback, works with virtually any format you throw at it.
- Available on many platforms; tag your files once in Kodi-compatible format, store the metadata on the file server along with the video files, and you can easily read them using Kodi on a wide variety of devices and computers. Alternatively, you can also set up a shared library a la Plex using a local SQL server, but that's a bit more involved.
- Endless customization options using the extension ecosystem. You don't have to use extensions (it's pretty complete in vanilla state these days), and for my simple needs I don't really need any. But just about everything you could wish for is available if you need it.
- Free and open source, no vendor lock-in.
I have a HDD attached to my AEBS and couldn't figure out how to connect but was able to easily and flawlessly connect via Infuse and NAStify.
I haven't tried NAStify. I like Infuse (it certainly has a nicer and more Apple-like GUI than Kodi, especially for things like fast forward/reverse during playback), but occasionally it has playback issues on files that MrMC plays without a hitch. Also, the metadata scraping naturally isn't always perfect (which is why I prefer maintaining my own local metadata using the method described above).
