Trying to use Adobe Encore to create a manual advance keynote BD-ISO

Question

Hi All,
Background:
I'm a media designer that produces corporate media content for a recruiting firm.
Objective:
I'm  trying to devise a way for presenters in our sales offices to run  standardized group interview and training HD keynote shows without the use of a DVD player or a laptop on their LCD screens.
Laptops=  every manager needs an apple computer and keynote software to run the  content + its messy to have to manage wired connections to the mounted  LCD panels all the time.
DVD Players= any updates that  are required to this content from time to time make the idea of  re-shipping physical DVD's logistically undesirable.
Proposed Solution:
Perminently  integrate a BD-ISO (menu) compatible HD media player into our office  setups that will run manual advance Keynote BD-ISO's (created in Encore)  where any new updates can just be downloaded from a central server in  the form of a Blu-ray master iso image by the end-user, dropped on their  USB flash drive, and played through the media player.
Here's the workflow I've come up with (Problem to follow):
1. Design a 1280x720 keynote presentation in Apple iWork's Keynote '09
2. Export a timed (Intervals: 5 sec/between each slide & 2 sec/between each object animation) h.264 | 1280x720 | 29.97 quicktime .mov file
3. Create Blu Ray Encore Project (1280x720, h.264, 29.97)
4. Import .mov file as timeline
5. Insert chapter markers at the beggining of every animation/transition (On diagram below- I'm talking about Ch. 3 & 5)
6. Insert a second chapter marker directly before each of the  previous set of chapter markers as close together as encore will allow (On diagram below- I'm talking about Ch. 2 & 4)
7. Set "end action" on each of the second set of chapter points (Ch. 2 & 4 below) to "Link back to here" so that the still image hold that occures after each "keynote animation" (thanks to the 2 sec hold time I set in the Keynote export- see step 2 above) is isolated so the playback loops on that chapter (which is a still frame because of the 2 sec pause between animations as set in keynote export).
Note on this technique: Idea is to set up the timeline and chapter end actions so that the playback loops on a few identical frames that exist between the two "extremely-close-together" chapter points (creating a "pause" effect) until the end user hits "Next Chapter" button on remote to jump to the proceeding chapter that contains the next keynote animation or tranistion.
Diagram:
(timeline->    ...---------------Ch.2<-- -->Ch.3(beggining of  animation)-------------------------------------(end of animation)Ch.4<-- -->Ch.5------------------------->)
8. Set "First Play," "Title Button," and "Timeline End Action" to Ch.1  of the timeline (so it starts there when ISO is activated and loops  back to there at the end of the presentation).
9. Export as "Blu-ray" Image
10. Load iso file on a USB flash drive, plug it into BD-ISO (menu) supported media player, and run the ISO and Voila!! = HD Keynote presentation running from BD-ISO file on a media player. PERFECT SOLUTION....
PROBLEM:
One of the most marketable (due to affordable price-point) BD-ISO (full menu support) media players is the HDX BD1. When I run the ISO file on this unit, it will play the first chapter, and pause and loop on chapter 2 like it is supposed to, creating the pause effect; But when I select "next chapter" it says "cannot_execute"- and I cannot proceed to the next transition/animation. I've previewed the setup in the encore preview feature and it behave's perfectly.
I'd be quick to say its a hardware issue but I've checked out several YouTube videos with people demoing this exact media player running and navigating feature film BD-ISO's (selecting "next chapter" and all) without any issues at all.
I've mastered something similar to this technique using DVDSP on SD DVD's, because DVDSP allows me to infinitley pause playpack ON each chapter point, not even needing the use of the "loop" feature I've set up in encore; But Adobe Encore doesn't offer a "pause" end action so I've come up with this as the next best thing. Although it doesn't play back properly on a full BD-ISO NAVI supported media player.
QUESTIONS:
1. Based on this setup, is there anything obvious I'm missing in Adobe Encore that would eleviate this playback problem on the media player?
2. Is there another authoring workflow within Encore that would allow me to acheive Keynote motion graphic, manual-advance slideshows?
Thanks for help in advance.

Hi Chad,
The most probable explanation is that Encore is creating incorrect navigation commands. It is well known and documented that Encore Blu-ray navigation works only for the simplest cases.
This should be easy to fix using BluStreak Tracer, Rivergate Software's upcoming post-authoring solution:

If you will prepare a small test case (1 GB or less) and post it on an FTP server, I will take a look and attempt to update it for you. You can contact me through our web site's contact page.
