The display name dosn't contain the PCI location. It contains the vendor id and device serial number (maybe not the right names) from the PCI card. The tuner /capture/crossbar devices have there own section within the registry.

I have looked into an old project and found the registry key for capture devices:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{65E8773D-8F56-11D0-A3B9-00A0C9223196}

Tuner:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{A799A800-A46D-11D0-A18C-00A02401DCD4}

Crossbars:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\DeviceClasses\{A799A801-A46D-11D0-A18C-00A02401DCD4}

The capture, crossbar and tuner devices from a TV card have the same DeviceInstance registry value. I have never used this information to create a filter graph. But maybe it works...
