CODE
[!] AVI: Stream 0 (video) has a non-zero start position of 1 samples (+42 ms).
   VirtualDub does not currently support a non-zero start time and the stream
   will be interpreted as starting from zero.


This is what I get when I import a video that I want to edit. I wanna cut a movie into 3-4 parts, but even if I recompress audio, audio is out of sync. (I did this a lot of times before, but this audio desynchronization never occured if i recompressed audio, only on videos that pop up this error). What am I supposed to do to fix the audio-syncing problems when this error pops up.

Go to Audio > Interleaving... and enter -42 into the audio displacement field. What's happening is that the video stream is being moved up to 42ms, so we can correct that by doing the same for audio.

This wasn't a problem with the older versions of VirtualDub (1.5 and 1.6 series). I have a audio sync built into all my captures, and now this message seems to pop up every time using the 1.7 series. Why not just make the adjustment automatically like the older version seemed to do? I'm curious why this has changed, and would not be considered a bug?

The old behavior was causing silent audio desyncs when the files were edited.
