corrections apportées :  
 
 
Removed the last SSE instructions from the YUY2->YV12 MMX conversion function.  
Added sanity checks for log file contents.  
Fixed a problem where the DirectShow filter was not applying brightness/contrast/saturation settings when starting playback.  
Reverted the DirectShow filter overlay operation to 4.0 (beta 2) style due to reports about decreased performance on some computers.  
Fixed a few problems in 2-pass VBR (sorry guys!).
Fixed a memory leak at the highest post-processing levels.  
Fixed a bug that coded macroblocks as "skipped" when they only differed in chrominance.  
Fixed a buffer overflow issue in the decoder.  
Fixed a problem where purple areas were appearing sometimes near the right edge of the picture (due to a bug in the encoder).  
Added support of log file format version 2. (This should add minimal ability for external programs to control 2nd pass.)  
Changed the encoder so that it assumes that 1 kbps = 1000 bits per second (the industry standard).Fixed a crash with YUY2 output where height = 16*x+2 and width != 16*x.  
Fixed more problems regarding decoding DivX 3.11 content.  
Added more fixes for decoding DivX 3.11 content with non-16*x dimensions

Difficile a dire, ça fait un petit moment que j'ai la 4.01 mais je fais que des petits encodages, et il me semble que ça a disparu mais j'en suis pas sûr du tout

moi j'ai pas de blocage donc....
j'ai juste des problemes de tailles du type je demande 700mo et il me sort 650mo !
et cela varri de film en film.............

Idem, j'ai pas encore eu de problemes entre les 2 passes, donc !!!
