Here are some of the highlights of the update:  
 - A new "Sharpening" post-processing feature that enhances texture and sharpens any DivX 3, 4, 5 or 6 video 
  - Optimizations for decoding and post-processing 
  - Performance enhancements for post-processing on HT, SMP, and dual core processors 
 
  Sharper video with the 6.2.5 decoder  
 The DivX decoder can now make your videos come to life with fine details and a sharp, well-defined picture, enhancing any existing DivX video - for free!    
 Faster decoding with DivX 6.2.5!  
 Our new decoder is also much faster than before, and that means lower CPU use during playback and/or better quality post-processing.  
 The DivX 6.2.5 is significantly faster than DivX 6.2.2 for playback - more than 30-50% in many cases, and up to 63% in the best case!  
 The results also show that the new sharpening filter, while greatly improving picture fidelity, also demands less CPU horsepower than the old deringing method.
