I don't know exactly
there's report that on G98 temporal works well. I believe in it
So, I suppose that PCI bus is limited

In order for either VDP_VIDEO_MIXER_FEATURE_DEINTERLACE_TEMPORAL or VDP_VIDEO_MIXER_FEATURE_DEINTERLACE_TEMPORAL_SPATIAL
to operate correctly, the application must supply at least 2 past and 1 future fields to each VdpMixerRender call. If
those fields are not provided, the VdpMixer will fall back to bob de-interlacing.

I could reach more less good quality output for 1080i at 50 , but I decided to come back to 1080p at 50 because that mode was
better than 1080i at 50 (I repeat mt TV set always informed me about 1080p mode , never - about of 1080i)
