- * Modifications:
- *
- * 29.03.2002 removed MBFieldToFrame - no longer used (transfers instead)
- * 26.03.2002 interlacing support
- * 02.12.2001 motion estimation/compensation split
- * 16.11.2001 const/uint32_t changes to MBMotionEstComp()
- * 26.08.2001 added inter4v_mode parameter to MBMotionEstComp()
