I have a new HP m9200t machine with BluRay/HD drive and I'm trying to
get the "DVD Library" option to show up on the Vista Media Center
interface without luck. This usually involves a simply registry change
specified in this KB article from Microsoft:

According to a thread on thegreenbutton, the HP Play DVD option in the
interface is not letting the "DVD Library" option show up in Vista SP1
because of some other registry key that forces the "DVD Library" to
stay hidden. Does anyone know what this registry key is or how to
enable the "DVD Library" menu item. Here's the greenbutton thread:

Any help would be greatly appreciated.
