DVD-Lab PRO... VTS menu and VMG menu...

[piassepierre]

Hiya... last week, or the week before... i posted here about DVD-Lab menus... now i can cope... but still there's a question about the 2 different kind of menus, VTS and VMG. I just can't see what i could do with VTS menu. VTS menu can show the selected item with a diffrent color, or any of the feature ! So i'm doing my thing with VMG menu. The problem is that VMG can't be root menu. So when i play my DVD, i have to push the Title Button on my remote to go back to the menu.

Anyone here know what "VTS" and "VMG" really are ?

To the DVD user it appears to be the same. But to the DVD player, VTS and VMG menus reside in different domains and are extremely important to the DVD author.

It is illegal for one VTS menu to call another VTS menu in a different title set. (By design.)

So, if you have two videos with different attributes (16x9 and 4:3, or different number of subtitles/audio streams), you need to pass flow through the VMG domain to connect to the different video in a separate VTS'. A good authoring project will align VTS' with title attributes.

So which one do you use? It depends on your inputs! If you only have one video or a group of videos with common attributes (video, audio, and subtitles), stick with one VTS. If not, you will need to cross over into VMG domain to access the oddball title(s). A VMG menu will help you accomplish that. (okay for the purest out there you can create an empty PGC 'passthru' with VM commands to accomplish the same thing, but still that PGC needs to reside in VMG domain....)

Note you can assign title to the VTS menu. In reality what happens is that title in VMG domain immediately calls your VTS menu. So it looks seemless to the DVD user.

Now, if you ever look at a commerical DVD and notice a single title in a VTS that is a few seconds in length, it is because that short title is the oddball warning screen with no audio and thus the DVD author correctly designed the DVD with this single title in its own VTS (title set).
