I downloaded "Subler". It did exactly what I wanted. I consider my original question answered. Otherwise, just a note incase I'm making a mistake . . . Subler (for my current situation) creates a .mp4 extension. I'm changing that extension to .m4v so this file's audio track is more "Apple Player App" compatible (according to the following article . . . http://forums.macrumors.com/showthread.php?t=441377 ).
You should not have to manually change the file extension in either HandBrake or Subler. Both are capable of producing M4V files when the proper work flow is used. In the case of HandBrake you must select the correct preset option(s) and with Subler the source file extension and file type must match and the imported tracks must be M4V file container compatible. Since I have no idea what you are doing, I cannot say if you are making a mistake in your work flow or not. I can, however, post a file showing you what I see whwn I use Subler to re-wrap data and/or adjust aspect ratio.
