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 nvidia mentioned http://us.download.nvidia.com/XFree86/Linux-x86/185.18.29/README/appendix-h.html 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.

I could reach more less good quality output for 1080i@50 , but I decided to come back to 1080p@50 because that mode was better than 1080i@50 (I repeat mt TV set always informed me about 1080p mode , never - about of 1080i) Goga _______________________________________________ vdr mailing list vdr@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
