Resume - Weird behavior
Tue, 2007-05-15 12:07 — Pierre-Luc
I'm authoring a DVD with DAE (Muxing with DSP) that has 5 VTS. VTS1 is the first play, with warnings & logos, then it jumps back to VMG PGC1 to play the short intro, then link to PGC2 that is language menu. Each language link to VTSM1 where all sub-menus and transitions are placed. Say I select French (First time I play the DVD), jump to VTSM1 PGC3, then press "Menu" button on the remote. It should resume VTS1 since it was the last video played, but on a certain Samsung model, it jumps back to the start of the menu (Which has an intro wih a loop point) and if I choose any movie from this menu, it will play the movie with the other language's settings (English, with subtitles) and vice versa.
Other behavior noticed on other players, say I played french movies, then jump back to VMG Title Menu (Language selection), then resume it will play the last french movie played, but with english subtitles.
The way it's authored is using GPRMs to set on/off audio/subtitles streams and activate/desactivate from PGC pre-commands.
Did I miss and authoring tip ?
Thanks!
Think I found it. Disabling
Think I found it. Disabling Root function while on the mains menus seem to solve the problem. If I test with Tracer, playing for the first time, viewing the warnings/logos (VTS1) entirely and let the commands execute, then jump to French menu, pressing Root get me back to the root menu (Dummy) and bypass the compare commands (To know if we chose french/english) to execute english settings. But if I press Title while Warnings are playing, then the Menu button resume correctly. So instead of modifying the commands, I'll just disable the Root function.
Thanks Ian. I was looking
Thanks Ian.
I was looking more deeply into the project and found that I left UOPs Title and Root enabled. Since the Root Menu is a Dummy PGC with pre-commands to route the navigation, I suppose that while on the French menu, if I press Menu, it goes back to the Dummy and process the commands then get back to the menu. And then, maybe there's a conflict within the commands because I track each menu with GPRM and route the navigation with compares. I'll look at this, but I suppose that if I disable Title and Root UOPs, Menu button will only act as Resume...
Hi Pierre-Luc,I think what you're
Hi Pierre-Luc,
I think what you're seeing is by design. There are times when Resume info is reset, and returning to a menu is the correct action. Please check out this link:

As it happens I have just recieved the DVD of Pan's Labyrinth from Amazon - it has an audio page where subtitles and audio can be changed, with a Resume button, which I think is similar to what you're trying to do. I'll take a look and see how it's authored.
As far as controlling resume goes, the only control you really have is to deny the Resume UOP on the menu.
Of course it's also possible you're just seeing incorrect implementation in the players - Resume is a tricky beast !

Could I prohibit resume
Could I prohibit resume function and allow it by setting a GPRM on the main menu ? Can I have any control over the resume function ?
