There are two types of 'scenes' in MPEG. The technical side are 
Group-Of-Pictures (GOP).  Is is possible to rearrange GOP without much 
trouble in MPEG.  Detecting GOP is easy.  The other side, context wise, is 
probably more difficult.  You can do a Chi^2-analysis to find peaks in the 
picture-difference residuals.  But is I were you, I'd save this feature for 
later versions ;-)

Cheers, Rolf
