Fix for Directx 9.0c ff/rw deinterlacing problem

[Wheemer]

as mentioned here: http://support.microsoft.com/default...b;en-us;885354 there seems to be a known issue with the Quartz.dll file that was included with the Directx 9.0c update.

As that page states, you can contect Microsoft for a fix apparently. However you can just copy the attached Directx 9.0b quartz.dll file to c:\windows\system32 overwritting the one that's there. This must be done in safe mode.

The stutter problem will be solved.

Hope this helps.

All of us in Snapstreams community have been going through this painful bug just like you guys.

I believe this was already fixed within Sage with the latest beta. The interfaces for DX9c changed and caused necessary changes for the applications using it.

However, this is great for those users not yet on the new beta!

EDIT: I wonder what affect this will have on the 2.2 beta users? If anyone is still having this issue do want to try?

[Cayars]

In safe mode copy the C version of Quartz.dll to Quartz-C.dll and then overwrite it with the one provided here.

If this doesn't help you or causes you a problem you can reboot back into safe mode and put the original back.

No brainer.

Yeah I went ahead and contacted M$
and got the hotfix
enjoy

here is the password and it is only good for 7 days

and consider making a back up

[Wheemer]

Thanks, but installing that brought the problem back for me...

[kny3twalker]

really
I got that from M$
and it addresses the quartz.dll
I can try to contact them this week
if I see it and let them know the problem has not been fixed

[kny3twalker]

OK well I tried the quartz.dll listed and I get locked video when trying to fast foward
then it unlocks after a sec or two and plays the part of the video at hyper speed

well I still think the better solution was using the directx9c version of the dll
then patching it
also I tried this above with and without the hotfix installed

I am going to contact M$ again tomorrow and see if I can get this worked out
I was having really good with other decoders just not nvidia with the hotfix
I will do some more testing

[Wheemer]

Well the dll I posted worked for me, then I installed the update you posted and it broke again. I then only copied the dll once more and it was back to gold. Mind you, I should have made it more clear that this was with BTV. I have only started testing Sage 2.2 after all this, and it is still perfect though.

[jan smit]

I have stutters since I did following updates:
directx90c
XP-SP2 (this one was needed to be able to install the hotfix).
Hotfix as described by kny3twalker (from MS)
I never had these stutters (frame drops?) before, the happen after I use skip fwd or skip back.
I restored a backup from before the hotfix (after SP2) and the problems stayed, so it is not caused by the hotfix itself.
I am now restoring back to directx90b (before SP2 and direct90c) and see what the result is like.

[turak]

Is this the same issue that people have with NVDVD/Sonic+VMR9+Hardware accel+SP2 causes massive stuttering?

[Wheemer]

As far as I know it is... I guess I should consider myself lucky. I was extremely please whne that dll fix made all the stutters go away... I'm a little dismayed that it's not helping others the same.

I guess I should offer a warning about trying this... Since I don't want people to have to format and go through hoops to get back to where you were.

It honestly made my Windows XP SP2 Directx 9.0c VMR9 MX 440 work perfectly again though.

[stanger89]

I can't say for sure, but I think there may be two separate issues here.

The Hotfix posted above is for:

When some video cards use a bob deinterlacing algorithm, video that the Video Mixer Renderer 9 (VMR9) has rendered may not play back correctly.

This does not seem to describe the issue kny and I have been seeing/discussing, which is a problem with field inversion.

[kny3twalker]

This does not seem to describe the issue kny and I have been seeing/discussing, which is a problem with field inversion.

are you sure these are not related problems?

CAUSE
This problem occurs because presentation times are not correctly assigned to samples when the video card deinterlaces content by using the bob deinterlacing algorithm.

this may not be the same issue
but when replacing this same quartz.dll the problem did go away
but I had long hangs after using fast foward

[stanger89]

No, I'm not sure they aren't related, just seems possible (likely?) that there may be more than one problem and this hotfix only fixes one of them.

[robertmcox]

My $.02:

Backrevving the quartz.dll (using the one Wheemer posted) solved the major SP2 stuttering and the FF bug for me! I'm not even trying the m$ hotfix.

XPSP2,Sage 2.2.2,Sonic VMR9 HW Enabled

[Narflex]

Those are 2 different bugs. I saw that MS hotfix awhile ago, but this would happen even when it wasn't using hardware bob deinterlacing.

Thanks Wheemer!

[Narflex]

Now that there's a workaround for this bug....if you'd like to use hardware deinterlacing under VMR9 with the SageTV MPEG Video Decoder set the following registry variable as a DWORD:

HKEY_CURRENT_USER\Software\MainConcept\DirectShow\MPEGVideoDecoder\ExportInterlaced=1

And also set this:

HKEY_LOCAL_MACHINE\SOFTWARE\Frey Technologies\Common\DSFilters\MpegDec\Deinterlace=0

(use the registry settings listed here, these are the ones that will work...you will see other ones that look like they will work also, but use these instead)

Make the changes while the media player is not loaded in SageTV (SageTV can be running).

The SageTV MPEG Video Decoder does not support DXVA for decoding acceleration; BUT the SageTV video rendering architecture does support DXVA for hardware deinterlacing under VMR9 w/ some decoders (such as the SageTV Decoder). FYI, if you try this with overlay, it'll probably look bad (Overlay only does bob hardware deinterlacing).

[turak]

replacing the quartz.dll worked for me also. I guess I can finally install SP2 on my main sage box.

[Wheemer]

Anything to help fellow PVRers!

Glad it seems to be working for some... I hope Directx 9.1 fixes this for sure. I thought I heard rumours of it coming out hopefully soon.
