Can't read a video after it is fixed with DivFix
 

I have this problem. I have a video which has some corrupted frames, then the video is desynchronized. So I open it with DivFix, cut out the bad parts and rebuild it. Then I open the fixed video, and there is this error message 'Unknown file format: DIVX'. At least, the original one works in BSplayer 0.86 build 493, even if it's desynchronized.
I use the brand new codec DivX 5.04
Any idea please on what should I do to read the fixed video?
Thank you.
