When your VCR records, Ad Zapper eliminates 95% of comercial time... ..Works with ... infra-red control... Anyway, does anybody know what is in the video signal that tips off this device that a commercial is coming up and when the commercial is over? On some cable channels like CNN and ESPN, they have the touch-tone sounds before commercials begin and end, so it wouldn't be too hard to key on those. But what about standard broadcast channels which have none of these tones? Is there something in the vertical sync bar? -- /| Todd Day (805)968-9352 |\ "I asked for a car, I got a computer.
