...I can confirm you're wasting your time with this =) That
particular dll is just an audio device mapper, and has aught
to do with the DRM component. If it's crashing there, then it'd
be more than likely that it never received a stream (because)
the DRM failed. Afaik, the DRM for this is undertaken in a 'real'
windows kernel (real low level stuff), and like other systems
of this type (hackshield, gameguard, big list...including the
DRM machanisms in wmp) don't work due to that sort of situation...
..you will find the 'magic' dll required, is a real windows kernel...
Cheers!
