I could really use some help...  I have been tasked with preparing a presentation (using Adobe Presenter 7.0.6) to include three separate video clips, ranging from 17 to 35 seconds, each embedded on their own slide.  I have tried several different ways of building these slides, but users intermittently report problems with the videos becoming choppy, often the audio breaking up and the video itself skipping.  It has been very rare that I myself would see these problems, the presentations typically run fine on the machine I'm working on, but others within the same network are experiencing the problems, and the problems have been duplicated outside the network as well.  I am at a loss; I have tried importing the original .mov files, I have tried importing converted .flv files that our IT department says they've dumbed down to a ridiculously low resolution (and it looks horrible).  Does anybody have any guidelines for size, quality, anything that they use when embedding videos into their presentations?  Anything'd help....  Thanks!
