Everything points to the fact that it is not possible to convert asx to mp4 or any other multimedia file for that matter, simply because .asx file is not audio/video file, but a link or playlist to actually multimedia file. You can convert different playlists to different formats, but that's pretty much it.
If you want to work or export .asx files, look on some dedicated playlist managers or similar programs.
