POSITION Placeholder for linked lists.

Quality Describes a quality message by indicating Flood or Famine in the renderer and specifying the percentage of frames to drop or add to optimize the renderer's performance.

REGFILTER Describes a filter in the registry.

REGFILTER2 Describes a filter for registration through the IFilterMapper2 interface.

REGFILTERPINS Contains pin information for registering a filter.

REGFILTERPINS2 Contains information for registering a filter through the IFilterMapper2 interface.

REGPINMEDIUM Describes a pin medium (as defined in the Microsoft Windows® NT DDK) for registration through the IFilterMapper2 interface.

REGPINTYPES Contains media type information for registering a filter.
