Hello All.

This is one solution for VCD which have different language tracks on each channel. File sizes for audio can get very big so leave ample space!

Programs to use Virtual Dub ( Downloadable at http://www.virtualdub.com/download ) and Audacity (Downloadable at http://audacity.sourceforge.net/windows.php ). Current versions are 1.5.10 build 18160 and  1.2.2 respectively.(Both are GPL /free)
Lame MP3 Codec will also be needed here.

Virtual Dub Part 1
============

1) Open your VCD dat file in virtual dub.
2) Click on Audio-> No Audio.  (Note Important Step!!!)
3) Click on Video-> Compression -> Choose either Divx or Xvid. (Note this step can be skipped if the movie on the VCD is a short one but not recommended . Equals Uncompressed  )
4) Click on Video -> Full Processing Mode.
5) Click on File -> Save as AVI -> Give a Filename
6) Once completed Click on Audio -> Full Processing Mode.
7) Click on Audio -> Source Audio
8 ) Click on Audio-> Conversion -> Channels-> Choose either left or right audio.
9) Click on File -> Save as Wav -> Give a Filename. (Note Do not choose compression here as u can only save as wav)
10) Close VirtualDub for now.
11) Check using Windows Media Player that there is no sound in the video.


Audacity Part
=========

1) Open the wave file. (You will see a wave form)
2) Choose Edit -> Select -> All (The waveform will be highlighted)
3) Left Click on any part of the dark grey area and press Ctrl + V. (You should now see 2 of the same waveform.)
4) Go to the down arrow of both waveforms  (top left hand corner (right of your file name))
4a) For the first waveform left click and click left channel.
4b) For the second waveform left click and click right channel.
5) Using the mouse left click and hightlight BOTH waveforms.
5a) Left click on the down arrow of the first waveform and choose Make stereo track ( Step 5 is the most important of all! If you didnt do this, one channel will be mono!)
6) Choose FIle Export as wave -> Filename ( the file should be 2 times the size of your original)
7) Close Audacity and open the file again make sure that there are 2 waveforms as created / or just double click and listen, both speakers should have sound coming out. (If you are confident that you have done it correctly you can skip this step).
8 ) Close Audacity.


Virtual Dub Part 2
============

1) Open the avi file you last created.
2) If you have choosen a compression method in part 1, then choose Video-> direct stream copy.
2a) If you didnt choose a compression medthod, Video-> Full Processing Mode, and Video-> Compression -> Choose Either Divx or Xvid.(Note do not put it as Uncompressed, RGB or your filesize will be very big if you do this)
3) Choose Audio-> Full Processing Mode.
4) Choose Audio-> Wave Audio -> choose the new stereo file you have created.
5) Choose Audio-> Compression-> Choose lame MP3-> Any stereo range is ok, I chose 44100HZ, 128kps CBR, Stereo .
6) Choose File-> save as -> FilenameNew
7) Finished!!!

I hope this guide is useful!
