    I'm not an expert on it, but someone surmised it in another thread. Apparently when Dish got sued by Fox over thier autohop feature the judge that dismissed the case specifically said something that implied the feature was OK only because they weren't skipping the actual content. I'll see if I can find the thread and post a link.

    I'm not Dan, and have never played him on TV. But as I recall...

    To steer clear of a lawsuit, first was the commercial skipping needed to be viewer requested. Not auto-skipped by the device or provider. But requested by an actual action. Like clicking a button.

    Second, it needed to return control to the viewer BEFORE the show started back up. Being a second early was fine. Being a second late (eg, missing a split second of the actual show) violated the copyright provisions of the show's creators. Don't ask me how or why, but that seems to be a sticking point.

    So by using real live people to mark the return point, and making sure that return point is not a split second late, they can avoid legal issues.

    This is all second-hand info on my part, read from other posts on this forum.

    I would think that these "live people" could handle a one hour show in just a minute or less if all they had to do was auto skip each commercial and verify that it didn't eat into the show. And they probably have a modified version of skip mode that jumps from the end of one commercial to the end of the next one.

    I don't know any activity that takes a minute. That sounds likely for far more mistakes than have been seen.

    They don't mark the commercials, they mark the show segments. Commercials can change from market to market, but the show itself and the duration of it's segments are static. So they mark the segment start/end points and assume the rest are commercials.

    As for how long it takes... who knows. Probably not long. If all I had to do was scan through a show on my TiVo and press a button at the start/end of each segment it probably wouldn't take more then a couple of minutes. If there is any sort of automated assist it could take less.

    I just wish these guys would err on the side of showing a tiny bit of the commercial instead of cutting out a tiny bit of the show.

    Based upon someone here who investigated the issues with the hopper lawsuit, that is exactly what is supposed to happen. No amount of show should be skipped.

    It's based on captions, so a shift in the caption alignment can throw off the segments.

    Also when they skip they have to jump to an I frame (or IDR in the case of H.264) to start decoding. So it's possible the skip point is OK and due to the encoding of your specific episode it might skip further in to the show then intended.

    Almost every time has shown a slight bit of commercial or the dark screen between for me.

    I've had it jump like a 1/2 second into the show and had to back it up to catch what they said. But that's rare. 99% of the time I see a bit of the commercial before the show starts.

    Not for me. I would say about 25% of the shows I watch have at least one skip point that is missing a second of audio.

    The audio may be more of a synching issue than the skip itself.

    I've seen (heard?) a few times when I trick play or come out of an app where it takes a fraction of a second to get audio back.

    If you are seeing video, then the skip marking is not the problem.

    The skip marking is the problem. TiVo is aware of the delay. They could surely build it into their skip marking system.

    I don't agree. I don't get the audio delay. Why do you assume it is a TiVo responsibility to adjust to every system?

    Because it is a bad experience. It would not ruin the experience to build a half second buffer on skip marking.
