@egur

the MC.ts is still problematic (wrong decoded)

the CD.ts is fine also sync wise

http://www.mediafire.com/?37kyc94d6n22tkf <- stops @ start

also i have a sample (very bad condition one) where i don't understand why Deinterlacing doesn't work on EVR Custom with ffdshow-quicksync but works fine on EVR (as if something adaptive would work on EVR (no flags needed) that's not being used on EVR Custom)

Upload of that one in progress (playback btw is fine for how corrupted this is only the Deinterlacing EVR Custom failing is what makes me wonder, several others shows this behavior too, though bitstream wise all are correct flagged though still sometimes EVR Custom Deinterlacing works sometimes it fails, when i look directly @ it and compare it seems for Mpeg-2 it always works but for H.264 it seems to fail interesting)

Does it mean Adaptive Deinterlacing works only on EVR and is it maybe possible to make it usable (from within Intels Drivers to work for other Renderer like EVR Custom as well ????)

Ahh seems the Problem is in ffdshow-quicksyncs MBAFF handling

Yep normal Interlaced Streams get correctly Deinterlaced on EVR Custom (Interlaced(PAFF))
MBAFF streams fail and only get correctly Deinterlaced on EVR

(hmm not sure yet but it seems the telecine fails on smooth cuts (fades) doesn't feel right on EVR Custom @ least)

Yep again EVR results are much better

ffdshow-quicksync Telecine Mpeg-2 EVR Custom (fail):

I guess that will be interesting to compare vs Nvidia
