I am having trouble with the audio interleaving. I have found that, maybe its just me, but the maximum i can offset the audio is 87ms. I need to offset it more to I believe about 125ms. Can anyone help me and tell me why and if the audio interleave skew doesn't offset more than 87ms?? thank you...

There's no 87ms limit. What exactly is happening? Are you typing "125" and VirtualDub is setting it back to "87"???

basically, i have extracted the audio from the movie and saved it as a WAV, (because the audio was previously saved in an incorrect format). I am directly copying the movie and adding the Wav to it. The problem is that the audio is ahead of the video, so if i type anything above 87.. .(i.e. 100 or 125), that audio does not process and no audio appears or is heard when replaying the finished dub. so i have tried typing other values but it only processes at 87 and below. i don't know why.. thanks for replying.

Very odd. unsure.gif

Right now, my only suggestions would be to reinstall VirtualDub, or use a WAV editor to add 125ms of silence to the beginning of your WAV. You could also try using an AVISynth script.

Still more info might be helpful; for instance, what is the format of the WAV? What is its duration? How big is the WAV (in bytes)? VirtualDub's audio filters are known to be buggy with huge files.
