Oh my god, so get this: The audio and video files weren’t imbedded inside the epub at all, nor were they at all included with the Kindle for pc release. I had to get a program called iTools to look inside my iPhone, and somewhere inside the Kindle folder there was a big folder with all the mp3 and mp4 files just sittin’ there. Perfect for Vegas.
Thank you for your help, schorman13 ^-^
