If I try to follow the guide from this site , with one divx I always get in the last page of the wizard that the lenght of the movie is 326 min but in reality it's only 150 min , but because it says its 326 min I can't convert it to fit a dvd-r. Now I checked the audio and video information it's for audio mpgeg-layer3 , and for video divx v4 . Does anybody know what I have to do ? And when I open this file in virtual dub I get this message: Virtual Dub has detected an improper cbr encoding in the source avi file (audi stream 1).The current preference is to rewrite the audio header with the standard cbr values during processing for better compability .This may produce up to 14073ms of skew from the video stream .If this is unacceptable ,decompress the *entire* audio stream to an uncompressed wav file and recompress with an constant bitrate encoder (bitrate 129.7 +-12.3 kbps) Do you want to rewrite the header ? Yes or No? The file plays in media player .And if I have to re-encode the audio with what program ?
