Sorry, I don't remember. My guess would be in IVTV, but I haven't 
touched my system since I originally set it up when .19 became 
available. You can probably find it in the documentation somewhere.

Be careful... we tend to find improvement where there is none. 8000 
is more than 6000 so it MUST be better, right? Well maybe. Do one 
more experiment: Set it ridiculously low just so that you see for 
sure what it looks like when it's set too low.

My pleasure!
