Specifies whether the core encoder uses the "Plus" feature.
Available only by using IPropertyStore.
This property is available only for Windows Media Audio Lossless.
If you leave this property at its default value of 0, or if you set it to 1, the core encoder decides whether the "Plus" portion should be used. If you set this property to 2, the core encoder does not use the "Plus" feature.
This property alters the enumerated media types, so if you set it, you must do so before you set the output type.
