ACM failed to suggest a compatible PCM format?

[Vertigo1]

What does this error mean?

The offending line is an AVISource command, which is using an XVid file with MP3 audio. I have other files of a similar format which work without problems so I'm a bit baffled. Any help greatly appreciated.

You don't have an ACM codec to decode the audio stream. Not all MP3 streams are acceptable to the usual ACM decoder (fraunhoffer ??)

The AVISource code is from VirtualDub so opening the file in VDub will usually give a similar error.

Try DirectShowSource to open the audioVid=AviSource("Blah.avi", Audio=False)
Aud=DirectShowSource("Blah.avi", Video=false)
AudioDub(Vid, Aud)
