[Live-devel] A stupid question (I hope)

[Clark N. Taylor]

With the -V option, I get:

Started playing session
Receiving streamed data (signal with "kill -HUP 32172" or "kill -USR1 
32172" to terminate)...

And then it hangs.....

I finally found another machine to compile stuff on, and it works fine 
as long as it is going between two machines (either machine can be 
client or server).  So, it is a problem only on one machine.
