    Hi Geoff,
        WMVCORE.DLL sould be backwards comaptible, but unfortanetly it's not. I
    didn't have much time to see what is going on here, but I can tell you for
    shore that something is wrong with that dll. After installing version 10, I
    did something for testing only. I removed new WMVCORE.DLL ( and
    put version Our application worked fine again.

    I'll try to provide more information about this...
