Are the SUPERBITS layer changes really "seamless"?

    Wanted opinions from those of you who bought them and on what players you are using?

    I didn't notice it while watching Crouching Tiger Hidden Dragon on my HTPC.

    No seams with the 5th Element on my HTPC.

    I dont think playing ANY DVD on an HTPC shows a layer change... I heard that like the computer has enough memory to buffer the video so the layer change is seamless because the buffered video is enough to go through the change...

    I seem to recall a layer change on my Panasonic RP56 for the Fifth Element.

    I did not notice a layer switch on Fifth Element SB.

    Does anyone know if this was intentional? Can it be done with all (yet-to-be-released) dvds?
    I dont think a "seem-less" layer change had anything to do with the higher bitrate. I would like to see this kind of thing more often. I cringe at every layer change when I watch something at home. Some movies will skip forward a chapter on my dvd player (Panny A-110).

    I believe that the "seemless" layer change uses "Seemless branching" to accomplish the task. I have yet to see it myself.

    Actually, I still notice a layer change (though very brief) now and then on my HTPC. But on most of them, you're right--no noticeable layer change at ALL on almost every DVD. This is especially nice on one or two DVDs I have (such as the 7th Voyage of Sinbad) that had clipped dialogue on my old Panasonic player. Now the dialogue is perfectly intact.
    And HTPC picture quality is exquisite [​IMG]

    You know, pristine video and superior audio be damned, I just want them for the seamless layer change. This should be advertised on the package.

    Most of the time on an HTPC, you don't notice a layer change. But there are some titles where there is a slight pause, and only then, when you know where the layer change is. I didn't notice the layer change with the 5th Element on my HTPC.

    I just watched Desperado and Air Force One on my Pioneer DV-343, which normally has a 1/2-3/4 second pause on layer changes. I'm happy to report I was not able to detect the layer change on either disc [​IMG]

    Just to let you know that I had a detectable layer change on both my Panasonic RP56 and my Pioneer DV-414. I don't believe I've heard the Superbits improving the layer changes.

    The Superbits discs are supposed to be authored for seamless layer transition. However, this falls outside of the letter of the DVD spec so it is possible that some players that cannot deal with "non-standard" authoring will not necessarily be truly seamless. These players will likely range from a slight pause at the transition to a full "crash" (a few first or second generation players).
    For the record, I have watched Fifth Element and Desperado all the way through and the layer transition was seamless on my Panasonic RP91, a player that normally has a 1/2 second pause at a layer change.

    IMO the seam issue should really be an issue of the DVD player and not the DVD disc, at least ideally. My Apex does not have any visible layer change, ever. My RP91 does, often.
    I'm glad superbit discs have addressed this problem to a certain extent, but this problem shouldn't exist in the first place, at least on higher end players like the RP91.

    I have to agree. If the APEX can do it, all DVD players should be able to do it. This isn't something the studios should have to concern themselves with.

    I watched Fifth Element on my Sony DVD-770 and did not notice any layer change

    Where is the layer change on The Fifth Element?
