Thanks for telling.
This makes things easier for me: it's safer to patch the bug like this
Just curious: is there any channel coupling when encoding 2ch (stereo) ?
Also I spot a link in which you were talking about how to couple multilanguage
I understand nothing about coupling but... it seemed like you had skipped the
most obvious coupling:
FL of one language coupled with FL of the other language,
FR of one language coupled with FR of the other language,
Isn't this the best way?
...or maybe I have not read the page correctly...

Yes, HeadAC3he, and the channels are not swapped.

See details here
I'm not sure if I should release such a patching-filter to the public. I want
Tobias to fix that!
