Invalid DVD Navigation Structure?

When I add an Extras folder to my DVDA (4.0) project, the project compiles okay, and burns without error. But the resulting DVD is not playable in any player or computer. DVDShrink reports "Invalid DVD Navigation Structure".

The content of the extras folder is only about 450Mb, and contains about 950 photos - well below the 2G, 10K file limit that the DVDA help reports. The folder itself is NOT located within the generated DVD folder.

Any ideas what could be happening?

(If I remove the pointer to the extras folder, the project compiles, burns, and plays perfectly.)

I'm not sure why it's screwing up using DVDA, but if it helps you can use Nero or Imgburn to do the same thing -- in another thread Chienworks I think explained some of the benefits from doing it that way.

Yeah, I resorted to trying Nero. When I try to include the Extras folder in the "Burn DVD Video Disc" project, I get an "Invalid format" error message for everything but the audio_ and video_ts folders. (I'm including the jacket_p folder, also.)

Probably using the wrong method in Nero?

Nevertheless, I've since found that I'm able to add "some" of the files to the extras folder, and burn successfully in DVDA...just not "all" of them. Which leads me to suspect some really, really f*'d up files somewhere. (950 images. And they all display fine in any image viewer tried.).

Have you tried using DVDA's ISO Image Writer (instead of burning to disc drive)? Maybe creating the ISO image first will help -- you can then burn the image file with Nero or IMGBURN...

Yeah, I always prepare an image first, then burn the image. Neither Nero or DVDA burned a playable disc. It was definitely a bad image (jpg) file in the extras folder.

I narrowed it down to a group of about 75 photos. There is one (or more) files in that group with a nasty problem.

Rather than do a binary elimination (remove 1/2 of them, burn a disc, test playability, remove 1/2 more, burn a disc, test....) at 25mins per iteration, I simply left that batch of photos out of the project. Oh well!
