I suggest using Windows Media on a data DVD for such things. You may want to check with your clients as to the size/resolution of their PC monitors. Exporting to 1920X1080 is often a waste of bandwidth when 1280X720 is all the more their monitors can handle. For example, I run two monitors at 1280X1024 each, so a 1280 video makes the most sense. And you get better quality at the same data rate due to the smaller frame.
Or, maybe use Flash or Quicktime. In anycase, unless your clients have a Blu-Ray DVD player, what is the point in using a Blu-Ray compatible format?
