What do you mean with "amule recognize an mp4 file-type as audio file" ? In file types on search pages?
i think so.
Never tried yet, but in "shared files" section I see mp4 files as audio file.
Maybe i'm wrong, but i think that most of people expect a video from an mp4 file instead of an audio-only.
If more mp4 files are videos then just audio, my suggest is to change the file type to video.
The better, imho, is to include mp4 file-type in both search type (audio or video).
ps.
sorry for my bad english
