I haven't been on here in a while cause i kind of gave up on it. I still don't own a red dazzle 100 but have the white one which is the 101. I am having the same problem as infinite93 and it seems i can choose the Dazzle DVC 100 in the video options but not audio. My friend uses the dazzle 101 for his broadcasting and he tried helping with it and i did everything he did but i can't select the dazzle for audio. It seems that vista could be the problem for this since he uses XP. I have tried everything possible to get this to work so im kind of sick of bothering with it so if there is a solution to this problem I don't think we will ever see it happening.
