:D After looking at my logs it appears that both Video and Audio bitrates are accurate. (Tested only with DivX 3,4,5 and mp3 ABR and mp3 CBR).
In the main window. When a codec Video codec is unknown, the Web link associated to movie data doesn't launch BSplayer web site but open the current dir in Explorer.
I've found 23 AVI that cause Access violation. They were muxed with a specific version of Nandub, modified par BST2k (itself), in order to edit the Audio streams label. (Fran?§ais & English is more convenient than Stream1 & Stream2, isn't it?)
The debug option seemed to be inoperant to dump the header, in fact it is and a 64kB file is created in the movie directory.
Do you want me to send you that header?
