    Audacity settings:Edit > Preferences > Import/Export > check 'Use custom mix'.
    Adjust the gain setting per channel (-6,-6,-9,-9,-6,-6).
    Export and set the number of channels to two.
    Join the lines to the boxes thus:
    Highlight a source box then click on the destination (click anywhere on an empty space to stop connecting boxes)..
    The idea is that the two left sources go to the left out.
    Two right sources to the right out.
    Centre and lfe go to both.

    Test by only selecting a small part and exporting.
    If the dialog is too low, adjust the center channel, export and check.

    Good luck.

    If the DVD player has optical, co-ax or HDMI connectors you get six channels out.
    If it has the basic L/R audio connectors, you get stereo.

    one last question how to increase its audio sound in audacity, i mean as it has 6 mono audio graphs where do i need to make settings for increasing its overall sound. Do i need to keep desired volume level at all audio graphs or there are some different settings to increase overall balanced volume?????

    There is no surround sound unless the player outputs six channels.

    Effects > Amplify.
    Save a small sample before exporting a two hour track.

    Are you dealing with one particular video or multiple videos?

    If you open the original audio and new audio in Audacity at the same time, are you saying that during playback they are out of sync with each other?

    You probably need a mixer designed to combine 6 into 2. They are fairly expensive so I figure if there is an easy, cheap way to combine tracks who would buy the mixers.

    it means remove a section of the audio out from the Main Audio stream,as an example it can be the beginning which lets call it 0 through to say 15,so now lets make those numbers in minutes it now becomes a section of audio that starts at 0 minutes & finishes in 15 minutes,you now have a smaller section of audio.

    removing a smaller portion of the audio makes it easier & faster to get the desired effect your after & once your satisfied you can then make the necessary changes to the main audio stream that you originally removed it from,this doesn't mean you have 15mins of audio missing from the original audio stream it will still be fully intact,all you've done is made a piece of audio to test
