Why is audio truncated when "shared"

Question

I have an hour of keynote presentations that have correctly working audio. (Recorded and dragged and dropped to individual slides.)
One short presentation (2 min) works perfectly when played in Keynote, but invariably truncates when shared to either iTunes or iWeb. (please see link)

This has a video podcast and a Keynote download link. The audio works on the latter; not on the former.
I have tried various kinds of transition changes, but nothing helps. And, besides, the existing transitions DO WORK IN KEYNOTE playback and when KN file is shared (and downloaded).
Any suggestions appreciated. Thanks.

Answer 1

This is awkward, but it did solve the problem.
Goal: To have the same picture (call it A) continue on screen as the show goes from slide 1 to slide 2. That is, to not have A “blink” when the slides change between 1 & 2.
(N.B. All slides have MP3 narrations; these were recorded in audio program and dropped onto each slide.
Problem: As long as I did not give picture A an EXIT transition, the audio on slide 1 was truncated when I “shared” the slide show to iTunes or iWeb.
I had thought I could just have NO EXIT transition for A on slide 1, and have no entry transition for A on slide 2 (which would avoid the “blink” between 1 & 2.
And when I previewed it in Keynote, THE AUDIO WORKED PERFECTLY, even when picture A on slide 1 had NO EXIT transition.
However, the truncation of audio on slide 1 did occur whenever I shared the same show to iTunes or iWeb (.mov).
I tried many variations including:
a “stop audio” transition with a lot of extra time at end of slide 1;
delaying the “start transition” in the “slide” window of inspector of slide 1;
...but all resulted in truncated audio on slide 1, as long as picture A DID NOT HAVE AN EXIT TRANSITION.
However, if I did give picture A an EXIT transition on slide 1, the audio was not truncated (but, of course, I had a “blink” between slide 1 and 2).
Solution:
Hide a rectangle (or any graphic) behind picture A on slide 1.
Give that blind rectangle an EXIT transition…
…but don’t give picture A an exit transition.
This fools Keynote: it segues from slide 1 to 2 without a “blink,” and the audio narration is not truncated.
But it took a day to figure it out. (I removed the link to the examples mentioned in first post.)
