Sounds like your TV just doesn't support 50Hz refresh natively, and trys to render it at 60Hz internally which just causes seemingly random hicups.
For the record, this is off-topic for this thread, please refrain from posting any general HTPC related questions here.

Thanks, curious to see how well this driver behaves with lav and madvr.

I'll let someone else test them before I go mess with my system again.

6 Days ago I reported the following in the MPC-HC thread.

- Looping ALWAYS goes wrong.
1. When playback is repeated, during the first reiteration there's no audio at all for the whole length of the file, but the seekbar-slider (how do you call it?) is moving normal.
2. When the seekbar-slider is at the end, it stops, but playback is repeated WITH audio. Another reiteration.
3. The next reiteration the seekbar-slider is moving normal again, but there again is no audio...etc, etc, etc.
- This only applies to MPC-HC + LAV Splitter (+ whatever Vorbis audio decoder). MPC-HC + internal OGG Splitter, or Zoom Player + LAV Splitter doesn't have this issue.
I was being told the problem would probably be LAV, although I didn't have the problem in Zoom Player for instance.
I've just installed LAV Filters 0.47 and I can say that the problem is mostly gone now (guess Aleksoid1978 was right after all), except that, when the first iteration starts, the first ˝sec or so of the Vorbis audio is cut off. But at least there's audio!

You don't need Virtu unless you want to render the video on a display connected to the dGPU. Maybe some transcoding apps will need that too.
QS decoder will work if a display is connected to an iGPU or even if you extend your desktop to a disconnected display.
If you want to use Intel video processing (EVR only), it must be on the iGPU connected display.

See this post for details on the setup.

The difference is that MPC-HC uses libmpeg2, which is just a completely different decoder. Its a bit faster in some cases, but has other bugs and shortcomings instead

Regarding new Geforce 295.73 WHQL driver, the MPEG4 ASP acceleration is broken again, it worked totally fine on 285.62 WHQL, and on 295.73 I am getting black screen on some files. I guess I have no choice but to roll back to 285.62.

If MPEG4-ASP is your only reason for that, you shot yourself in the foot.

MPEG4 ASP works fine here with that driver and CUVID DXVA.

Edit: Got a GTX 570.

What's the consensus on the new driver? Worth updating to?

Here the new 295.73 driver is a big step using mpc-hc, lav-cuvid, madvr on my 9600M GT:
- the VPU usage (h264,vc1,mpeg) is around 20% less then the v285.62 !!! (i can see it with the help of nvidia inspector)

So, finally, I can watch a full hd content (1920*1080) on this old rig ! (Eg. the first couple of minutes of Defiance, without frame drops)

Ps: MPEG4-ASP doesn't work for me ... (and not with the old v285.62 driver)

I have a 570 as well, and MPEG4-ASP isn't working for me.
Note that it doesn't break with every file (but alot of them), and of course its off by default.

But then again, i don't really care about HW decoding of MPEG4-ASP.

Well I am totally satisfied with 285.62 WHQL, except dxva(c/p) bugs, but I fill sad and angry that nvidia screwed fresh driver release.

I've got 470 gtx and I doubt there is any difference in VPU engine between 570. Also it's not like all MPEG4 ASP movies are not working at all, there are some files that playback fine and some that don't, I think you just haven't encountered that files yet.

By the way what do you mean by saying DXVA? MPEG4 ASP is only supported via CUVID.

Can you upload a 2 minutes sample somewhere, which is working?
Thanks

True, I just checked an encoded sample with Handbrake/ffmpeg.
Not a huge problem, MPEG4 ASP should be completely replaced by H.264.
I don't see any reason to use it still.

I have a question about deinterlacing with DXVA2 native:

I see there are no deinterlacing options for DXVA2 native. However, if I use LAV DXVA2 along with MadVR in MPC-HC with deinterlacing OFF, I still get a properly deinterlaced image. What is doing the deinterlacing? Is LAV applying YADIF in this situation?

DXVA2 native does not work with madVR, so it would be falling back to software decoding. If you have YADIF active, it would use it.

Hi nev, Does lavvideo use wmv9 software decoder for wvc1?

I have been having trouble when using the software decoder built into lav video. I notice with process explorer, that in the "GPU Graph" tab, that the "System GPU Memory" tab increases by a few MB perhaps once a minute, constantly until it begins to eventually effect playback performance.

I can't reproduce when decoding h264, only WVC1 so far (testing with the dark knight blu-ray). I can also reproduce with ffdshow wmv9 decoder only so its not lav specific at all. All I'm mentioning it here for, is if lav video does use wmv9 as the vc-1 decoder in software, maybe you might like to know about this issue in case it might mean you'd like to look into it / or make any particular changes in lav video temporarily based on it.

I use the avcodec decoder, so the issue must be something else.
GPU memory is also very unlikely to be influenced by a software decoder.
