Yes, but the tv stations put in a short period of black & silence before returning to the show. I'm pretty confident that this is what the 'zip through commercials' vcrs cue on.
Darned close. The article I saw said it detects the period of black and silence and puts a `notch' on the tape at each such switch. The notch can be detected at fast-forward speeds. My question is - what happens if there is black/silence *between commercials*? How does the VCR know that what follows a mark is show or merely the next commercial? -- Simmons' Law Of Alcoholic Expectations: The best stuff always happens after the meeting, when everyone goes to the bar.
