You can use Windows Explorer (I dont know the equivalent sa iMac) to browse through the contents of the Stream Folder under BDMV. If there is only 1 very huge m2ts file that most likely contains the entire feature length, then that should be easily playable under both Simple BD or Full BD Nav. If there are like bazillions and gazillions of m2ts files in numbered sequence, that's seamless branching. OK lang sana if the movie is divided into sooooo many small m2ts files in a regular number sequence, but if patalon-talon ang numbering, then it's possible that the sequence of scenes will be messed up under Simple BD - in which case, kailangan ng Full BD Nav in order to access the correct Playlist. Kaso, enabling Full BD Nav also means enabling all sorts of protection on the BD - Region Lock, Cinavia, Playlist Lock, among others - which in most previous cases, are effectively bypassed via Simple BD mode.
Sa Full BD ISO, I dont know because all my Full BDs are in BDMV Structure. Perhaps there is some sort of "ISO-Exploder" utility so that you can analyze the contents of ISO container. But the thing is, I notice that all Full 3D BDs are in single ISO naman - makes sense because you basically have 2 video streams played simultaneously, hence I imagine having 2 BDMV Structures for the left and right eye would be rather complicated. Ive got the 3DBDs but not the appropriate player and TV so I dont know if some Full 3DBDs (in ISO) are also CINAVIA'd.
With regard to PCH playback, there is BD Nav Setting within the SETTINGS. Initially, I set it to Full BD Nav but then I realized there are films or contents where I simply want to go straight sa main movie without bothering to know the Special Features. Thus my BD Nav setting is PROMPT - meaning everytime I play a Full BD, the PCH asks me if I want to play via Simple BD (which is quite faster to load), or Full BD Nav. I also noticed that there are Full BD rips that would only play perfectly (the main movie I mean) EITHER by Simple BD OR by Full BD Nav, but not both, hence, it's convenient to be able to select between the two playback/nav modes on every Full BD. In the end I think the determining factor is still the ripped BD itself.
sa ISO and sa BDMV, how can we tell if its Simple Navigation BD lite or Full Menu multibranch navigation? there a tool we can use?
