Just a quick post as my mind has been blown! I just learned that you can do a "save as" when in PowerPoint and select "Windows Media Video" or an "MPEG-4 Video". I won't even tell you that crazy/strange work-around I have done in the past to turn a PowerPoint into a video. Hoping this saves someone else all that extra work! :-)
*Note: I was using Microsoft PowerPoint 2013. I was told that 2007 should have the same option.
** Note 2: You can also save your slides as pictures (JPEG).
