The KSPROPSETID_TSRateChange property set defines a set of properties to effect time stamp rate changes. This property set can be used to implement fast-forward and rewind capabilities. KSPROPSETID_TSRateChange is not restricted to DVD-only usage, and can be used for any MPEG2 stream.

typedef enum {
    KS_AM_RATE_SimpleRateChange=1,
    KS_AM_RATE_ExactRateChange=2,
    KS_AM_RATE_MaxFullDataRate=3,
    KS_AM_RATE_Step=4
} KS_AM_PROPERTY_TS_RATE_CHANGE;
