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.

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

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!

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.

- 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)

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.

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

Not a huge problem, MPEG4 ASP should be completely replaced by H.264. I don't see any reason to use it still. I wrote "CUVID DXVA". |

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.
