Legend of Korra and Avatar: The Last Airbender (TV, not movie) full soundtrack

Hi
I’m interested in obtaining a full soundtrack for both ATLA & LoK, does anyone have one or is anyone working on one? If not, I would like to know:
1. If the soundtrack is available on the DVD (Nickelodeon, region 2 encoded) as a separate audio channel/layer and how to extract it
2. How to extract from the rest of the audio it if it isn’t on a separate layer from the rest of the audio?
3. If there’s any guides on how to do the above on the forum
I’d like to collaborate with anyone who’s more experienced at this than I am if possible, I want it to sound the best it possibly can because I love this show and want to contribute something to show my love of it. Since it doesn’t seem likely that any more soundtrack will be released from dickelodeon, I also intend to release the soundtrack to somewhere that other fans can get it, and most likely will post a link on here
Thanks

here’s a thread: Thread 97989

Unfortunately for A:TLA there isn’t a full release of the show in 5.1 surround sound so it’s impossible to do what you’re wanting to do.

LoK however did get a full release in 5.1 surround on blu-ray only. The DVDs only have stereo.

I haven’t looked into it myself and how they mixed the 5.1 surround so I’m not sure how possible it is to do.

I’m aware of that thread, however i was unaware it had been updated

aren’t the blu-rays america only (damn you, dickelodeon!)? If yes, i’m not sure i’d be able to get them to work. is the 5.1 surround only the score or the whole audio?
the only way to get a full ATLA release is from Zuckerman or by manually editing it?
