Remarks

This filter is not available to DirectShow applications. It can only be used through the Video Control on Microsoft Windows XP Media Center Edition.

Whether encryption is actually applied to the content depends on the copy protection policy that is set by the content owner and/or broadcaster. Microsoft Windows XP Media Center determines the copy protection policy by reading the broadcaster's copy protection flag (CGMS-A). If the flag specifies no encryption, then the resulting file will be accessible by any DirectShow-based application that uses the Stream Buffer Engine.

The output type matches the input type, except the subtype is changed to MEDIASUBTYPE_ETDTFilter_Tagged.
