OK, I have done this, and followed the other instructions in Scott's 
excellent HOWTO. And it all seems to work fine -- data goes along the pipe, 
cpu cycles are used...but the viewer window remains black and there is no 
sound! What is going wrong?

Here's my command and the messages it put up. Any help very welcome.
