Any info on "iVCD by Fl0ppy" custom matrix for XviD?

Does anyone know anything about this quantization matrix?

Does 'i' stand for interlaced maybe? Can it be used for progressive videos?

VCD Video can be:
¼ D1 NTSC (SIF) 352x240x29,97p 4:3
¼ D1 NTSC (SIF) 352x240x23,976p 4:3
¼ D1 PAL (SIF) 352x288x25p 4:3
so no interlaced. May be this is related to a software named iVCD.

iirc XviD had no interlaced encoding mode and custom quantization has nothing to do with interlaced or progressive,....
