Audio/Video skipping during certain slides

Hi All,

I have been working on a screen simulation and until yesterday everything played back smoothly in the preview and also published.  Yesterday I made a couple of minor edits (replaced the audio on one slide (from Audacity), added a couple text captions, changed the font for several captions) and I started noticing skipping in the audio and video on a few slides (this happens in both preview and published). I have the filed saved in My Documents (not a network drive).  I have two versions (one with no skipping from 2 days ago (A) and one from yesterday with the skipping (B)), and have be playing with both trying to find the root cause. 

On version A I tried to recreate the changes I made to B, pausing to watch after every change to find the cause.  It ended up being text captions I added to the bottom of half of the slides (simple text and says "Questions?  Contact ....").  Without this text the project plays fine.  Because verion B is more updated I figured if I just removed this text it would also get rid of the skipping.  However, this did not work. Has anyone else had any problems with audio and video skipping (almost like a scratched CD) throughout projects?  This project is not large (35 slides) and not overly advanced (software simulation) in Captivate 5 on Windows 7.  Any thoughts or ideas would be greatly appreciated!
