right, ive installed virtualdub and added one of the dodgy files, this is the message i get

VIRTUALDUB HAS DETECTED AN IMPROPER VBR AUDIO ENCODING IN THE AVI SOURCE AND WILL REWRITE THE AUDIO HEADER WITH STANDARD CBR VALUES DURING PROCESSING FOR BETTER COMPATIBILITY. THIS MAY INTRODUCE UP TO 16234MS OF SKEW FROM THE VIDEO STREAM. IF THIS IS UNACCEPTABLE, DECOMPRESS THE *ENTIRE*AUDIO STREAM TO AN UMCOMPRESSED WAV FILE AND RECOMPRESS WITH A CONSTANT BITRATE ENCODER. (BITRATE: 124.2 +- 13.9KBPS)

does that make any sense to you folks?? and one last thing.....where will i find a user guide for this, the virtualdub site doesnt have one and im not too sure what im doing. i will persevere for as long as i can.

any help will be appreciated.

thanks
