Right i know similar questions have been asked before but still nothing exactly the same and so no solution.

I am trying to convert a 5.1 surround interleaved WAVE file into a 5.1 AC3 file.

I drag the wav file in and select "audio to ac3" selection and then click encode.
It takes about a second and returns a 0Kb file that nothing recognises.

I have taken a look at the conversion log and it reads as follows:

FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard

Can't resample. Aborting.
Mac OSX universal build for ffmpegX
libavutil version: 49.0.0
libavcodec version: 51.9.0
libavformat version: 50.4.0
Input #0, wav, from '/Users/markwiggins/Desktop/PassingThrough.wav':

Stream #0.0: Audio: 0xfffe, 44100 Hz, 5:1, 4233 kb/s
Resampling with input channels greater than 2 unsupported.Abort at ffmpeg.c:1628

Why can it not resample more than 2 channels?
If anybody can help with why I cannot convert please help.

Thanks for any help.
