Newbie who wants to know more about seamless branching & multi angles

[monks19]

Hi, I'm a bit new here (as a poster, not as a reader) and I hope to find some answers here.

I would like to know if there are some good softwares that I can use to add & change (instead of deleting) some elements to some DVD & Blu-Ray projects after the main elements has been done with an authoring application like Adobe Encore or Sony Dvd architect pro, like seamless branching, aditional video angles &/or pop-up menu (Blu-ray only for that one) ?

I know that some applications like BDedit, Pgc edit, DVD rebuilder, BD rebulder can achieve some of those modifications, but which one, for which support ?

I know that something has been done by this guy on his blogue, here (http://www.precomposed.com/blog/2013/10/another-encore-blu-ray-bug-solved/), by using Encore and BDedit.

Any recommandations/suggestions for this ?

Thanks to answer

For what you want to do, best thing is redo the project. There is no other way around.

Jon Geddes, is modifying playback nothing major. Yours no where close.
