BDedit - BD structure edit

[Emulgator]

Oh sorry, I was only passing by and wondering if I should upgrade, being on 0.51b6
But I would draw some conclusion from

maybe Post #17, Playlist -> STN -> PlayItem
If I find time I will look through what I have got multi-angle.
Ratatouille has beeen mentioned, (papers, recipes, inscriptions appearing in different languages matching the preferences).

IIRC it was just the choice of playlist which swapped the other stream in.
And the DVD-A BD multiangle test projects I had muxed did it similar IIRC.
For a fulltime 9-angle project I had 9 .m2ts of similar length laying in STREAM folder.
m2ts makes it rather simple compared to DVD-Multiangle where the VOB indeed had to be muxed interleaved.

Just checked Ratatouille:
At certain points in the timeline playlist 00001.mpls splits into 3 angles
and can swap stream segments of same length in:
inscriptions, paper tearouts in FR,IT,DE.
This is for non-seamless, I guess.
