Blue-Ray Object: "Menu"; Export File Not
Found--Any Clues?

Trying to build a Blue-Ray DVD in CS3 (version 3.0.1.008). Project has motion
menus and previews without errors. Upon trying to build either a disc or image I
get the error

Blue-ray object: "Menu"; Export file not found.

Where "Menu" is the name of one of the sub menus in my project.

Has anyone seen this error? What is an Export file? When and how does it get
created?

I have the pleasure of closing out my own question. I found the following post
that was the clue I needed.

It would appear that the Blue Ray build process is a lot more sensitive to file
naming. I brought into my project a menu that I used as a starting template, I
edited it in Photoshop and then renamed it in Encore. During the Blue Ray build
process Encore rendered the menus to the original template names, but when it
needed them to build the DVD it looked for the files that had the new names I
had given the menus in Encore.

Here is the fix. I exported the final menus using the Save as Template function
in Encore. I then re-imported them as menus and relinked them to the DVD assets.
Everything worked fine from that point on.

I have the same issue when burning blu-ray discs. Although I have not renamed
any files . Its so frustrating. Encore is so buggy it is unbeleivable. Its like
its never been tested.

If anyone can tell me how to fix "Blu-Ray Object: xxxx Export File Not
Found" I will be very appreciative. I have several projects I cannot burn.

The files I have imported are Quicktimes, they transcode fine. Its when i burn,
or create image I get the error. It previews fine. There is nothing odd in any
of the file names. I have not replaced any assets. I have no motion menus.

You should always use elementary video and audio streams in Encore.

Muxed program streams have to be de-muxed for processing, and then re-muxed
again at build time. That's just asking for trouble.
