System: Windows Vista SP1, ReClock 1.8.3.0, CyberLink H264/AVC Decoder (PDVD8 ), Radeon HD4670

During playback of H264 MKV file with DXVA acceleration ReClock info window ("ReClock Properties") show "23.976 fps, 1280x532i, NV12 12 bits". I understand about "532i" instead of "532p", but colorspace isn't NV12. According to KMPlayer info output pin of decoder has following properties:
majortype: MEDIATYPE_Video({73646976-0000-0010-8000-00AA00389B71})
subtype: Unknown({3231564E-0000-0010-8000-00AA00389B71})
formattype: FORMAT_VideoInfo2({F72A76A0-EB0A-11D0-ACE4-0000C0CC16BA})

When playing MPEG2 files ReClock reports "25.000 fps, 720x576i, NV12 12 bits" or "25.000 fps, 720x576p, YUY2 16 bits" while actual values of decoder output pin are:
majortype: MEDIATYPE_Video({73646976-0000-0010-8000-00AA00389B71})
subtype: Unknown({EE27417F-5E28-4E65-BEEA-1D26B508ADC9})
formattype: FORMAT_VideoInfo2({F72A76A0-EB0A-11D0-ACE4-0000C0CC16BA})

"According to KMPLAYER": What do you think the "subtype: Unknown" is?

From uuids.h:

Code: 
// 3231564E-0000-0010-8000-00AA00389B71  'NV12' ==  MEDIASUBTYPE_NV12
OUR_GUID_ENTRY(MEDIASUBTYPE_NV12,
0x3231564E, 0x0000, 0x0010, 0x80, 0x00, 0x00, 0xaa, 0x00, 0x38, 0x9b, 0x71)

I'm not sure about correct GUID I was quoted but it's DXVA for sure: CPU load about 3-5% (in opposite to 30-60% software decode).
"ReClock Properties" window allow me to turn on "Show VSYNC on screen" and "Tearing test" but nothing visible exist in both cases.
In case of DXVA shitched off "Tearing test" is visible.
Here is first part of info from KMPlayer on decoder output pin:
