@Boo Boo : Congrats, you could convert your file ! And the result is amazing !
To answer your question, yes, I checked many times before saving the audio file, I think it was ok.
@xpect : Thanks for the .rar, I've just tried with your files, and guess what, it ends up with the same error !!
Here is what I did :
1) In the DOS prompt I typed: "avi4hv.exe space.avi"
2) avi4hv displayed the file infos ( FPS, H. resolution, V. resolution, bit depth etc.) and asked: "Is this correct (y/n) ?"
3) I typed: "y"
4) It displayed: "audio file (must be 8-bit uncompressed WAV)"
Is there something I do wrong ? I'm clueless...
I don't understand why it does not work, this time I only used the files present in the .rar archive.
Any idea ?
