I play it with Cyberlink's pd8 decoder,but "20fps bug" happens.
My display card is HD3200.

Thank for remind me about new x264 builds.

I re-encoded sd41.mp4 with x264 rev.859.

mpc-hc dxva decoder works fine with below setting

max ref frames:
without bframes=15
with bframes=11

Resolution: (x264 rev. 859+ encoder settings)
320x240,720x480,720x576,1024x544: (--level 4.1 --ref 11 --mixed-refs --bframes 3 --b-pyramid --b-rdo --bime --weightb --direct auto --filter -2,-1 --subme 6 --trellis 1 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --me umh)
or (--level 4.1 --ref 15 --mixed-refs --filter -2,-1 --subme 6 --trellis 1 --partitions p8x8,b8x8,i4x4,i8x8 --8x8dct --me umh)

Sample:
SD41_720x576_ref11_bf3.mp4
SD41_720x576_ref15_bf0.mp4

SD41_1024x544_ref11_bf3.mp4
SD41_1024x544_ref15_bf0.mp4

Hum ... over here (GeForce 8600 GTS) it does not work with more than 4 Ref frames, so I have a question:

Could this difference be related to the graphics card ?

On my 8800GT to not work fine woth more than 4 Ref frames.

Possible it is on all Nvidia Card, because on Radeon all 4 my sample, where Ref frames>4, play fine with DXVA, people on russian forum test:

Ok. So that could be the reason of the "bad" reputation of nVidia cards regard DXVA ...

On the other side, MAYBE the link below "x264 Encoding Options for Hardware Compatibility & DXVA", pointed by @MatMaul should be reviewed considering Hardware by Hardware.
Over here (with 8600 GTS) I can not have sucessfull DXVA with more than 4 Ref frames, even for very low resolution like 704x396.

G80 nVidia GPU's like 8800gtx only support motion compensation (DXVA1/XP) wile G92 GPU's like 8600gts or 9800gtx support bitstream (DXVA2/vista (or xp+evr)), i.e. full video decoding. MPC internal decoder only supports bitstream.

I have 8800GT 512Mb on G92 GPU with support bitstream, but error on DXVA, when ref num>4.

test on XP+WVR9, XP+Evr, Vista+Evr .

try changing your driver then

Changing, and many time, many version - NO WORK.

Sample that i Uploading on my not work with DXVA

On MPC-HC Internal Decoder - Black Screen
On Creative h264 External - "20fps bug".

I have same problem on nvidia 9600GT. Previously i had HD 3200 integrated on 780G chipset motherboard, and before than i haved HD2600XT AGP on older machine. Both radeons decode fine with DXVA support, on every video render (VMR7/9), with both MPC-HC or Cyberlink H264 decoder's, never have problems with drivers and similar. But with nvidia 9600GT, first time when i installed driver, playing video in MPC show corrupted frames, than i update to lastest drivers found on nvidia site, now cyberlink decoder work fine, but MPC-HC return me gray screen, and there is no playback. I want just to say nvidia's prue video is suck comparing to radeon's UVD. I don't know why ppls love nvidia.

why love nvidia - because I by 8800GT first for gaming -> is it number 1 in this price+speed segment.

I wait that Nvidia fix driver, and DXVA be work fine - now i decode software, my C2D@3200Mhz work fine with it ...

well HD3870 is more payablle than oldish 8800GT. Prices in my county is almost same for that card's. And 9600GT also have near price. But 3870 gives more, stuff like DX 10.1, Assassin's Creed have support for shader 4.1 and DX 10.1. I realy don't care about less 5fps less in games with radeon cards.

nvidia the way it was ment to be played

thats why I love nvidia
watching videos is second to gaming
its true for a lot of people

but both ATI and Nvidia need to man up in the drivers field...

The bugs with the nvidia purevideo decoder will have to be reported to NVIDIA, this is the only way a driver update will fix the drivers

This topic is a bit messy. May I suggest the following to the regular posters here:

Someone (with a DXVA capable graphics card) should open a new topic for discussing these "DXVA compatibility" issues. The opening post of that topic should be updated on a regular basis to contain a summary of the content that is discussed in the topic.

Contents of this opening post could be:
* Links to sample files. For each file technical details (levels, max ref frames, etc) should be included.
* A list of graphics card models that are (somewhat) compatible. If a card has some limitations with regard to the type of files that it supports, then that info should also be included.
* For each sample file, maybe list which cards are able to play it and which are not.
* The rules for getting DXVA playback: compatible card, H.264 bitstream requirements, no intermediate filters, etc.
* A FAQ that answers frequently asked questions and gives solutions for common problems.

Hi everyone.

It does not seem there were any comments on this. Is it possible that this could please be fixed?

I have just remuxed Elizabeth - The Golden Age on HD-DVD (VC-1) and it actually has noise (flashing white blocks) in the extra 8 lines. In PowerDVD the original disc does not show these. Even TheaterTek does not show them playing the remuxed mkv. However, MPC-HC (still using the official release, not any beta, don't know if this makes a difference) shows these last 8 lines, which are never meant to be shown on any hi-def disc.

I know I can manually move the picture down "one notch" and get rid of the extra lines, but this is messy to do with every hi-def disc.

Like CoreAVC, could there be an option to crop 1920x1088 to 1920x1080, for AVC and VC-1?

Thanks
