It looks like Kannada is kn-IH, at least according to The Movie Database web site.  Telugu is te-IN (as you indicated).  I can add them to the settings, but I can't say what it will mean in terms of the content that gets delivered to the scraper from TMDb.  I don't do the maintenance on the movie scraper, so someone else would need to do that.  I'll try and make some time this weekend to add them.  Once I request an update to the main repo, it can take awhile for someone else on the team to do a review, so I can't say how long it'll be before the change is available.

@pkscout ,

Thanks for acknowledging.
Yes for Kannada, it is "Kn-IN", My mistake.
TMDB is following "ISO 639-1", as per here Languages.

It should be, "Kn-IN" & "Te-IN".

When I tried to add "Gaalivaana" series to my library, then only I noticed cannot find Telugu in Languages.
I ended up adding under Tamil language (Dubbed version) for time being.

Then I searched and realized Kannada is not there in the list.

FYI, Hindi, Tamil, Telugu, Malayalam & Kannada are the 5 major & prominent language movie industries in India.
Others are minor contributors only.

Sounds good.  I added them in the Nexus version of the scraper and then back ported them to Matrix.  Hopefully they'll get reviewed and approved in the next week or two.
