Reduce the glossary back to 1 term and see if it loads.

Subject: [Xerte] Glossary, video,	visibility issues in HTML5 preview and deployment





I am in the final phases of completing a LO in XOT 2.0 and I have run 
across an array of issues that I am hoping someone may be able to help me solve. 
I moved this resource from Captivate to Xerte and would hate to have to move it 
back at this point.
 
A bit of background first: The resource is for language learners who will 
not be connected to the internet so the final deployment is planned to be via 
USB flash memory. The includes a large glossary of terms (100+ terms), video 
(mp4) and audio (mp3). As it will be on flash, higher quality video and audio is 
preferred. HTML 5 is also preferred as we may deploy online at a later date and 
want users with Apple devices, such as iPads, to be able to access the 
resource.
 
At the start of the project I added the text and images and all appeared to 
preview fine. I exported a SCORM 2004 deployment to demonstrate the resource and 
it too ran fine in Moodle 2.2. I then added the audio and all still seemed 
alright. 
 
Adding the video, however, brought about some unwelcome changes. The video 
will be embedded in multiple places as it is used for different parts of the 
instruction. The video would play fine once but afterwards it would not load 
(nor would it load on subsequent pages with the same video). The video is also 
on a quiz interaction page, on which it appears to be embedded twice (two video 
players appear stacked on top of each other). 
 
At some time during this, the main template disappeared during previews. 
Page content does appear, and unticking the visibility:hidden box during debug 
in browser brings the template back. I believe I have seen this posted 
previously so I am not focusing on this issue here but perhaps it is relevant. 

 
Finally, when I expanded the glossary (which also initially played fine) to 
include all terms, it seemed to break the LO. When I try to preview the LO, the 
template does not appear nor does the page content. Changing the visibility in 
browser debug does bring back the template but not the navigation buttons or the 
page content. Also, when I tried to export the LO it no longer sends the files 
to a zip; rather, it creates an empty zip file and puts the files in the 
USER-FILES folder for the project.
 
One other point to further confuse is that if I change the default engine 
to Flash, much of the resource shows up properly.
 
Any ideas? I was hoping to demo this for final vetting in two weeks but in 
this state it is unusable.
 
Thanks for any help that can be provided. I can attach xml or other files 
if that is required for further digging.
