I have attached a link to text file showing the decoded dll file. Just can't make modifications to it. I did tell the PDVD provided MSVCR71.dll to RETN when V@YAXPAX@Z = memfree.

Anyone interested in helping decode the MK4 keys are welcome to join in.

For those looking to assist. (decoded) HDDVDAdvNav.dll is called from HWCtrlMgr.dll.
