Well - last night was a challenge, but thanks to Derrallg, Sharonp and others I think I have solved my problems. So for other Leopard users. The version of Nicecast I am using is: 1.9d1 I have my Source set up as Application: Skype It automatically hijacks when I broadcast. I was getting a high-pitched feedback on the line - lowering the output volume in my system preferences seemed to fix that. Lisa and Alannah could not be heard properly. I updated my Skype and am now running version: 2.6.0.184 and that seems to have fixed that. I streamed a couple of times in the Sandbox and it seems to be OK So thanks all. I know it will not be the last of the problems. Problem-solving is part of the game. Susan
