I upload a set of images about various NV Decoder + NVPP setting. As you can see there are some problems in smart(same as auto) + nvpp mode.


My HTPC Setting :

Player : Zoom Player 4.03

Decoder : NVDVD (Registered TheaterTek 2.0 + 2.02 Patch)

FFDSHOW Setting : ASharp - 18

Lanczos4 Resize to 1280 x 720 (no chroma and lume sharpen)

Output Color Space : RGB32

Test Scene : DVE (Display Setting Chapter)

Video Card : nVidia FX5900XT

CPU : P4 3.0C oc 3.3G


ps :

nvdvd decoder DXVA can not work in ZoomPlayer. No DXVA work fine.

DScaler5 filter work better in Film DVDs, but bad for video and combine DVDs. We want a soft decoder that is as good as Faroudja's video processor. And we no longer to switch video decoder or video settings according to the media type.

why do you output to rgb32 ?

for dvd playback YV12 should be more appropriate.

Over 90% of DVD’s are film based (progresive).

I’ll take the decoder that works best over 90% of the time. :D

Why do you select NVPP when you are in SMART mode? With your video card, NVPP is done in hardware when you select SMART deinterlacing. Selecting SMART and NVPP on your video card will cause image problems. SMART is not the same as AUTO either.

Someone tells me that hardware NVPP only actives in DXVA mode, But I can not make DXVA works with ZP.

I found that RGB32 colorspace has much fresh and natural color.

RGB24 should give you the same results, I don't believe that the extra 8 bits are used and I know that the RGB channels are identical in bit number. I think they are/were there for an alpha channel. You can save yourself some bandwidth and make your pictures smaller :D. Note that it probably doesn't really matter.

it might matter as for nvidia cards YVU2 and YV12 work in 16-235 color space when rgb24 or rgb32 work in 0-255 colorspace

Except that my DVD collection is more like 50%.


Also, you need a $40 program to use this "free" decoder.


Sorry, but I'll stick with NVDVD...
