  If I understand how it works correctly, it's because the player is able to play back the source material in a large number of ways (on the fly). You could have multiple clips on the screen with different geometric properties, multiple audio tracks, cuts, etc--and the player will just play back the appropriate parts of the media at the right time with the specified scaling, masking, and other attributes. The app itself is approaching obsolescence, and had a limited feature set to begin with, but it could do what you're talking about.
  
  Also, many high-end non-linear video editing software will read many codecs natively and archive the highest-quality files for use when you actually encode your project (to avoid fidelity loss caused by multiple encodes and decodes in the editing process).

  You could try [VirtualDub](http://virtualdub.sourceforge.net/) since you haven't got it working yet.. I have only used it with AVI though..
