For DTS-HD streams, I think you should look to the profile returned by mediainfo (MA, etc...) as the codec is always DTS. 8/6ch are correctly detected (extended/core streams).

will check, thx

Refreshes and lang in sub's filenames are working. Great!!!
I don't need it but may be it's worth to do the same (lang detection) for external audios (xxx.en.ac3 / yyy.fr.dts) because I'm not sure these files have proper embded metadata.

Good to hear.
yeah, i think we could add the language here too...

I can manage to translate to french and spanish but I'll need some time.

np.
This is always an ongoing task...

I want to try against my main library (2000 movies/concerts, 60 tvshows) to see how it compares to Mediaelch (almost unusable for me). Is there anything (any known bug) I should be aware?

Not any that i'm aware of
The only destructive part might be the "rename & cleanup" of movies, where we remove all the not needed files (according to your settings)
Better try it on a single movie first, then do the bulk cleanup

So, even if the nfo contains mediainfo XBMC don't use it and rescan the file? Was this the case with Eden?
I you remove from nfo will it be possible (if in the future you consider to add this possibility) to filter by resolution, audio codec, audio lang, sub lang...

I guess yes. XBMC always reads this on it's own... (for displaying all the nice graphics)
Since we have the values in the DB, we could filter for everything....
