Well i might have been a little harsh, but your post readed like someone that does not contribute but complains about an Open and Free Software just because it did not does what you want.
Kodi core team focus on the project and does little extra ports, and they probably would never submit a version to LG software shop, like they never did with the Android version. (there have official builds for Android but you have to get them outside the Play store).
That program you are talking about is probably a port of Kodi/xbmc that does not respect the GPL_v2 of Kodi and that is probably why i only found it on a Turkish forum. Also its side loaded for what i could translate... that means that you can download it to a USB drive and use it on you TV (personally i'm going to try it). If you translate the forum were its posted the binary you will see that is not on LG App store but is sideloaded.
But for what i can figure out from the blog where its uploaded the latest builds, this program does not seem to be a rip-off of the Kodi code but an entirely independent project... but then again there is little info about the code (that i could find out).
Also you can get the latest build of it here: http://mkvod.blogspot.pt/
So try it and share with us the experience if you please.
