I agree, the strict option does help a lot. It's hard to be objective 
about it but it seems just about as good as it was when the ALL option 
was first introduced. I'm wondering if my picture is confusing it. My 
cable box produces light and dark lines that scroll up the picture 
constantly. Very subtle, but it might confuse the commercial scanner.
