Well, not fully MERLIN compliant, but another way of playing sound/video perhaps along with Merlin.

Code:
; Minimum DLL version shell32.dll version 4.71 or later 

; Minimum operating systems Windows 2000, Windows NT 4.0 with Internet Explorer 4.0, 

; Windows 98, Windows 95 with Internet Explorer 4.0 

; $FILE=Path and name of file to use

; $Show sets whether or not to show the player 0=no 1=yes

; $Wait says for the script to wait for the file to finish before closing 0=no 1=yes

; If files listed in the $MediaList are videos it will display the player even if you set it to no
