Figured it out!
It had to do with the form of .swf file I was creating using Sorenson. And after reading this helpful doc:
I'm still not sure why using "F9" settings to create flash files in Sorenson screws up the PPT animations once they've all been put through Presenter... but that's been the result.
What
does work is using a lower .swf setting for video to flash in Sorenson:
AUDIENCES
WEB
DOWNLOAD
FLASH
SWF (Flash 6+)
F6 (Med)
>> 30 FPS
>> "Embed file"
