What is related to VCASMO? Because VCASMO is also integrated your video and PowerPoint (converted as JPG) together for synchronized playback. If VCASMO support SMIL, the first thing we think about is enhance the offline version. You can download the presentation as SMIL format. Which you can playback it in Real Player or Quicktime (both support SMIL).
Please tell us what you want VCASMO can support with SMIL.
