Limit on bkgrnd audio or video?

The only limit I'm aware of is that all menus on a disc together cannot exceed 1 Gb.

That's interesting. I was planning to make a DVD for a presentation using menus with background video on specific topics, thinking the video would loop and there would be forward and backward buttons to navigate through the presentation. The program would have approx. 60 menus and would be 1 hour long.

Are you saying that this is not feasible because the background video on the menus would exceed 1 GB?

The DVD Spec limits the size of all the audio/video information associated with menus contained in a single VTS to 1GB in size. You are also limited to 99 menus, though that limit wouldn't be an issue for you.

To accomplish your project, you'll need an authoring program that gives you a little more control over the VTS's so that you can spread your menus across multiple VTS's and not exceed the 1GB limit. I can't offhand think of a way to do this with DVDA but it can certainly be done with DVD Lab Pro.

Thanks for the info. It is good to find that out before investing a lot of time in the presentation.

I hit this limit recently putting together a Tai Chi DVD - I was trying to use a separate menu background for each of 85 forms.

I have now achieved the same thing in DVDA by adding the whole movie separately many times, each with its own In and Out Points

Let me get this straight, Peter.

I can render all my menu backgrounds together as a single .mpg, then add that long mpg to each menu as a background and isolate the video for each background using in/out points. This will bypass the 1GB limit for menu media?

Sorry, I didn't make this very clear

First I had the whole movie included several times so viewers could choose different sections to view. These had their own in and out points, then returned to that menu.

Then I also wanted to have a looping movie of each of the 85 individual forms. This was what I originally tried to do by using short movies of each form as Menu backgrounds and this is when I hit the 1 Gb limit.

Instead I created a separate Menu for each of 4 Levels, and these menus contained about twenty buttons each which simply played the individual short movies, and these movies had End actions linking back to themselves in a continuous loop.

Doing it this way only lacked one feature which the Menu method had - a button to interrupt the loop and return to the previous menu. Instead I put a note on each Menu that users should use their "Menu" button to return.

Hope that's clearer now!
