These are my results, yes different from other PD versions and would appear still not correct. The small test case evaluated BD and DVD created discs as well as the PD preview feature. I used a basic PD menu template with no first play video. Burnt disc were evaluated on a PS3. Other formats and players may results in differing behaviour, I did not test.
So if “Start from the menu page and play all titles sequentially” is selected
BD H.264 (burnt disc)
Insert Disc: menu is played and play when selected plays entire disc and returns to root menu
Scene: plays starting at selected scene and chapter and plays all remaining and returns to root menu
DVD HQ (burnt disc)
Insert Disc: menu is played and play when selected plays entire disc and returns to root menu
Scene: plays starting at selected scene and chapter and plays all remaining and returns to root menu
PD Preview BD
same as burnt behavior above
PD Preview DVD HQ
same as burnt behavior above
So if “Start from the first title and play all titles sequentially” is selected
BD H.264 (burnt disc)
Insert Disc: skips menu when disc inserted and plays all titles then plays menu and ends on root menu
Scene: plays starting at selected scene and chapter and plays all remaining and returns to root menu
DVD HQ (burnt disc)
Insert Disc: skips menu when disc inserted and plays all titles then plays menu and ends on root menu
Scene: plays starting at selected scene and chapter and plays all remaining and returns to root menu
PD Preview BD
same as burnt behavior above
PD Preview DVD HQ
same as burnt behavior above
So if “Play the selected title only” is selected
BD H.264 (burnt disc)
Insert disc: menu is played and play when selected will play entire disc
Scene: plays starting at selected title and chapter and plays title only and returns to title menu
DVD HQ (burnt disc)
Insert disc: menu is played and play when selected will only play the first title completely and returns to root menu
Scene: plays starting at selected title and chapter and plays title only then returns to title menu
PD Preview BD:
Menu plays, play when selected will only play the first title completely and returns to root menu
Scene: plays starting at selected title and chapter and plays title only then returns to title menu
PD Preview DVD HQ
same as burnt DVD behavior above
