 You will need VDMSound to use it

 It works fine with the white label cd versions of DOTT and Sam and Max [S+M without voice though :( ].
 It should work with your DVD packaged version, but may need slight modification.
 If it doesnt work, email me. Once we get it working I can include it in the next version.
