Screen Recording: Last few seconds cut off when published

I made two screen recordings in SL today that play perfectly in preview.  However, in the published version, the last few seconds are cut off, which cuts off the last word or two. 

Also, in the published version, I scrubbed ahead in the video to get to the next slide (there's no "Next" button, but there is a trigger to move to the next slide when the timeline ends).  When I did this, it moved the video ahead, but did not seem to advance the timeline because it did not advance to the next slide for what seems to be the amount of time that  I scrubbed ahead.  Is this the wrong trigger to use?  

I've tried a few things, but my brain is just fried, and I was hoping someone might have some ideas as how to fix this.
