Audio recording problem (DxTory)?

I use Dxtory to record video games that I play with my friends. I have one line for my mic and one line for my game audio/my friends. I want to be able to have a line for each of them, so game, mine, and my friend that are separated. I tried a program called "Virtual Audio Cable" but it didn't work as it didn't recognized my speakers and what not in the Audio Repeater.

What would be the best way of going about this?

Also, I'd like to add that my friends mic is picked up on both the audio stream for my mic and the game audio. Does anyone know why?

Thank you for any one who answers.
