I agree with Billy on this one. I've done a ton of menus before...but the more menu items there are - it becomes a tad difficult to manage.

But...maybe this will also help you on how many menu items you can have.

(Billy correct me if I'm wrong). You have a limit on menu size (collective) of 1 gig. If all of your thumbnails/images/menus exceed this...DVDA will tell you it can't produce it. So, if you can fit 1000 thumbnails in under 1 gig....go for it.

I can't put my finger on it right now but I think I recall reading that there is a limit of 99 items. I don't recall if it was in total or per each sub menu which is on top of the 1 GB limit thing. Maybe someone else knows for sure.

I believe the limit is 99 chapters per title.

It might also be worth mentioning that if they hope to have all 26 of 'em on ONE page, the thumbnails are gonna be very bitty. If you don't include text labels (e.g., employee names below their pictures), the thumbnails can be a little bit bigger.
Of course, you can split the set across 2 or more menu pages.
The only hassle with that is, because DVD-A doesn't yet have End Actions, then every time the viewer wants to access the thumbnails, they have to go back to the TOP-level menu and drill down to the thumbnails menu(s) from there. i.e., you can't bypass the top-level menu and go directly back to the chapters menu(s).

And one more thing... just (re-)learned this by frustrating experience over the past couple of nights:
Make sure your thumbnails line up in nice, neat rows -- same number of thumbnails in each row.
Otherwise, if you use "creative" spacing of any kind, the risk is that when your viewer uses the arrow-buttons to jump from one thumbnail to another, the sequence of jumps might turn out to be NOT what you intended (and your viewer expected).
Contrary to what you might intuitively expect, the "ORDER OF OBJECTS" shown by the object-numbers on your DVD-A workscreen does NOT control the sequence in which you jump from thumbnail to thumbnail on a chapter menu. "Order of Objects" might have some effect on the sequence, but the POSITIONING of the thumbnails seems to be the most important factor.

I'll post this in this thread cuz maybe it applies, and the other posters' might know
the chapter limit (which is 99 like it is in most authoring s/w packages)
I'm creating a dvd video owners manual/tech training disc
which will include 20 topics (vegas projects or mpg's)
for the sake of keeping it simple if each one of these topics are selectable from the main menu
can they each have up to 99 chapters? not that I would need that many for each , but the total chapters for the entire disc would be likely more than 99.
