Further reading of MSDN shows the following:

    "Upon presentation of media, the Shell searches the ROT for a component
implementing IQueryCancelAutoPlay. If one is found, ***the class identifier
(CLSID) of that component's moniker*** is extracted."

This suggests that your IQueryCancelAutoPlay interface has to support the
IMoniker interface as well.  IMoniker derives from IPersist, which has a
GetClassID() method for retreiving the object's CLSID.  I will bet that your
interface does not support that properly, so when the OS goes looking for
your object, it can't verify the CLSID so your interface doesn't get called
to block the AutoRun.  If you look in your QueryInterface(), does
IID_IMoniker (or similar) ever get requested?

I do notice that there is a SHCreateQueryCancelAutoPlayMoniker() function
available as well.

BTW, how are you adding your interface to the ROT in the first place?
