Hi, I am a noob and I have a problem that I am sure you guys will know the answer to straight away!

I have a wmv file that I am using avisynth and VirtualDub to convert to avi format. However, I cant even get past the avisynth part of the conversion because the lip syncing is all out of whack.

The avs file just has the following coding in it:

Code:
DirectShowSource("F:\Karen\Promo1.wmv", fps=15)
AssumeFPS(15,sync_audio=true)
When viewed normally as wmv it all works fine, but when I view it via the avs script the audio and video have differing FPS :S

Any ideas about what is going wrong?

Thanks in advance
