Convert PMF to WAV

You should be able to easily convert PlayStation Portable Movies directly to WAVE Audio Files (.pmf to .wav conversion). Attempting this typically relates to users trying to extract the audio track (WAV) from a PMF movie file.

It seems there aren't many tools and converters supporting such conversion. Your best bet is using FFmpeg or VLC Media Player, since these utilities allow users to import PMF movies and export their extracted audio track in WAV format.
