VMG or VTS... does it really matter???

[GangstaRap]

I'm using DVD Lab Pro,
as you probably know, every project starts with a poppin window askin whether i want
to start a "VTS Menu + Movie" or a "VMG, VTS Menu + Movie".
i usually author one DVD Movie (one MPG) so i just pick "VTS Menu + Movie",
but now, i have 3 seria's episodes and i'm a bit confused...
is it really necessary to pick the VMG project?
cause, even when i'm making a VTS project - i still given the option to add another "Movie" section to the "Working Window",
so i'm asking - whats the point in this VMG thing?

Thanks!
Any help appreciated!!!

If your episodes are all the same resolution, aspect ratio and have the same audio then they can all be put in the same VTS, so you only need to choose the single VTS + movie project.

If you want to mix resolutions, aspect ratios or have different audio formats then you have to use multiple VTS's. This is when you need the VMG, as it bridges the VTS's to allow oyu move between them.
