This isn't really the forum you should be referring to for tech-support, especially if you want a quick answer.

Apart from Obrusnine being right, I'd also like to note I don't think what you're asking is possible and if it is, it's probably pretty hard to achieve... I've managed to get sound out of two sources at once (TV and Speakers, while hooked up to my laptop) but they both play the same audio... and as it seems to me, you want to play your game with headphones while somebody watched a movie on VLC, without the audio clashing... if this is possible, it would be difficult for an everyday computer user to achieve.
