Does exist a VFW mpeg2 I frame HD codec YUV 422 in all the world?

That is not matrox mpeg 2 I frame codec, because it internally converting rgb-yuv gatto grr and I like a only yuv?!?

and That is NOT ffdshow because it don't work well as mpeg2 decoder

Or does exist a VFW decoder of mpeg2 YUV 422 files generated with FFMPEG?
