       Taken from the audio classes. I suspect the same is true for the video classes.
       Anyway it wont hurt having this here.

       Get extensions of additional audio procs. These extensions may be specified by
       newly installed IO procs in MMPM2.INI or by using the Multimedia setup. For
       example the MMIOMP3 procedure for reading MP3 files adds the MP3 extension this
       way to the system. Extensions already handled by a specialized class will be
       filtered in the called REXX script e.g. MP3 so only unknown extensions end up here.

       Strangely enough wpclsQueryInstanceFilter() is called during wpclsInitData() so
       we query the extensions here before calling the parent.

       FIXME:
       The check is only done once during initialization. This is a little annoyance for
       the user because new extension specified in the settings will only be picked up
       on next WPS start.
