I'd be interested in this. In going through my programs last night, I
found that all my non-CBS recordings were about as close to 100% as I
can imagine. The only one with issue was CBS and with strict detection
turned on I believe it missed on break and had one short 12 second false
positive and another 0 second false positive (makes me think we should
have some kind of minimum bound on commercial length inclusive with
strict detection to eliminate such short and obvious non-commercials).
Anyways, if you have an example of how to apply this filter to that
channel, I'd appreciate it and would love to test it's results.
