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.

Yes, wavy lines or static can play havoc with the detection. If you have a noisy signal, the "blank" frames won't seem blank since they may have very dark pixels and a some very light pixels so the code won't pick them up. I tried to work around this one time by assuming the frame was blank if only X% was light while the rest was dark, but that caused false positives as well like for instance a nighttime scene of people driving in a car where most of the frame is dark but there are a few light spots. It's definitely an art but getting better over time I believe.
Yes, it absolutely is getting better. It's a very hard problem and you've done a great job getting it working as well as it is, even with the wavy lines... :-)
