help needed to download video with 2 languages

[yogi7]

Hi everyone,

I'm trying to download the video from this link
http://misatv.ro/prima-pagina/gregorian-bivolaru-21-decembrie-2012/
using rtmpdump but I have some issues.
The player from that link has a menu where you can choose the language of the audio stream: Romanian or English.
If I use rtdmpdump with rtmpexplorer it downloads the video with the audio English.
I tried to figure out how to download also the video with Romanian (URL snooper, Wireshark), googled the internet of similar problems but I couldn't found any solution.
I even don't know if there are 2 audio streams in the video that are selected from that menu or if by selecting the language from that menu the video stream is changing.

I appreciate any help,
thanks.

I think I found how it was done.
I extracted the mp3 from FLV file with flv extract and the left channel is the romanian language one, and the right channel is the english one.
I would search for a way to separate them now.

Any audio editor can do that. Like audacity.

yes, true, but is joint stereo and it seems I cannot separate them without re-encoding.
