D_J you are completely right! But, as I have "only" three Playstations to test my projects, I do whatever I could... discovered that the old PS3 Fat is sometimes faulty - can't read certain retail BDs, or skip some parts, or can't read anymore BD-Rs when it plays faithfully them some months ago - I could rely just on the new PS3 Slim and PS4.
When they play right, I think the disc is well authoured, but maybe I'm wrong, because Playstations are well known to play almost everything... maybe is MultiAVCHD the guilty, because it seems EasyBD Lite "menuless" discs works better...
The last option, that SHOULD be investigated, is the fact that MultiAVCHD uses the old version of TSMuxer, that, accordingly to many, it could have some compatibily issues... now, I replaced that old version with the newest one - that is supposedly free of those problems; when I'll finish the next project, I'll author the BD-25 using this new version, and try to find some friends with a BD player to test the disc with as many players as I can.
Meanwhile, you can always download the project, and use just the main m2ts file, untouched, to make your own BD, or play it directly in your PC or hardware players.
Every other who burned the project in a BD-R; please, report your feedbacks here, thanks!
