With the help of people involved with the video4linux project I've 
gotten to the point where my Kworld 120 tuner properly scans for ATSC 
signals.  So, I've made a first pass at populating the Kworld 120 wiki 
with the steps which I took as well as some extra suggestions people 
have made.  Emphasis on the "first pass", as I have some cleaning up to 
do.  If you are in dire need of instructions you can have a look.  Of 
course you'll be obliged to offer feedback either here or by editing my 
scribbles on the wiki ;-) :
