The blank-frame detection code that is used during the auto-flagging thread
does not have a max.  It just keeps checking for what it thinks are
commercials and flags all of them.  The on-the-fly blank frame detection
code has a 300 second limit on the commercial length.

I had working code at one point that was detecting this on test files
fairly accurately, but don't know what I did with it. :(  I have had it on
my TODO list for a while to reimplement the rating symbol detection.  I also
looked at using the vbi info but didn't delve into the code enough to
get that working (also on my TODO list).  If someone else wants to take
a look at either of these, feel free.
