Started playing session
Receiving streamed data (signal with "kill -HUP 3837" or "kill -USR1  
3837" to terminate)...

==============================================================

Also, I looked at the resulting file, and it had an intact JPEG. Only  
one. I assume it writes the last frame received, overwriting the  
previous frame?



Anyway, it looks like I need to figure out where to hook in my  
client, and I'm ok,I think.


Thanks,


Neil Alexander
