i everybody, i hope somebody can help me, i have downloaded a avi-xvid which plays perfect on my computer, but when it comes to splitting so i can burn it(virtualdub 1.5.10) i get this message... Virtualdub has detected an improper vbr audio encoding in the source avi file and will rewrite the audio header with standard cbr values during processing for better compatibility. this may introduce up to 691 ms of skew form the video stream. if this is unacceptable, decompress the *entire* audio stream to an uncompressed wav file and recompress with a consstant bitrate encoder. (bitrate:127.7 +/- 1.4 kbps) this has started to happen on a number of films but at the beginning was fine, please can someone tell me what this all means
