I *am* talking about seamless branching. I didn't say everyone could do it, I said there are tools available to do it on PCs, so the tools are available to everyone. If you can't do it, then you are doing something wrong - we do it a lot and it works - seamlessly. Have you tried to do it? Give it a go and see how you go.
Now some early MGM titles reportedly didn't do it properly, that is correct. (Though all the ones I have work fine).
But hey some commercial titles have crappy layer changes too, some commercial DVDs have crappy telecine and bad colour grading. Does this mean that correct telecine, good colour grading, perfect layer changes can't be done? No.
The Robocop R2 set works perfectly on my gear, as does the T2 edition, not even a stutter at the branches. If your DVD player isn't up to the task I suggest you replace it with one that meets the full spec. It may be a bit short on RAM.
In general if a DVD player pauses on a layer change, then it will definately pause on a branch as well.
