I'd like to watch a video with sound on one computer, share the screen, and have the sound heard by the other computer, not going through the speakers. i.e. it should transmit the video from my screen and the same sound that's going to the speakers, right off the sound card.
It is possible to do on XP, but not on 7.
I have tried to use the stereo mix as the sound source, but it seems that skype blocks that.
