SL2 - Slide with video not in jump order very slow to load

I have a slide that contains a video that is jumped to if the user needs to review the video during a 7 slide quiz. No matter what I do, I can't seem to get this slide to open quickly. The video is in MP4 format and about 100 MB (4 min video). The output is SCORM zip.

When the slide is the next slide (as a test), it loads fairly fast (a few secs). But when it's out of order, it takes close to 25 secs.

I've tried:

1. Creating a master slide with the video in it and creating a slide with this layout - didn't help.

2. Adding the video as a layer in each of the quiz questions. Even with copy/paste, the project ballooned to 1 GIG and was unmanageable. SL didn't seem to store just one version. I got 7 copies of the same video in the SCORM zip file!? (To be completely accurate, I copied the layer and the layer contained the video from quiz slide to quiz slide - maybe this is not the same as copy/paste the video?)

3. I tried jumping back to the video slide (as a test) and it was slow.

4. Faking it as the next slide with a  jump to slide trigger with a condition that was never true (hoping to fool SL2 slide load code :-)). I thought this was very clever. SL2 did not agree. lol

Out of ideas. :-(

Thanks for any suggestions.
