You're right, I was assuming that, but if what you suggest is correct wouldn't all recordings start on the minute or half minute (or some related constant)
after a START signal had been sent by the broadcaster?
If the Hummy IS checking every 30 seconds for a START signal, how could my recording (post #4) start 45 seconds after the opening scene which, on the second Corro, is about 5 seconds after the start of the theme tune. This adds up to a 50 second delay from the beginning of the program to the start of recording. I have seen a delay of as much as 1 minute 20 seconds on a program some while back.
