MPC-HC software MPEG2 decoder has inferior image quality compared to others like Microsoft DTV decoder. I now know why. The decoder needs an option to force NV12 output colorspace. This is because NV12 is compulsory for vector adaptive de interlacing.
Slightly offtopic: I tried forcing NV12 using FFDShow. It says it is outputting "NV21, VU". Quality is excellent but does anyone know if NV21 is better/worse/same than NV12? |

Thanks JanWillem32 regarding your feedback on by video jitter effect with certain files. Here is a screenshot of playback from one of these files with evr-cp. Even frame time correction doesn't seem to get me my perfectly flat green line back. As I say, playing many other content on my pc like m2ts, blu-rays, etc will show perfectly flat graph in evr-cp so I'm not sure how I can workaround this issue with the files I'm having issues with.
Any suggestions anyone, how to get rid of the green jitter in my video presentation graph above. |

I'm still using ffdshow for MPEG-2 because the internal decoder and Microsoft doesn't support 4:2:2 sources, but most people probably don't have any of those anyway. Quote:
At least for Win7. I don't think anyone ever tested and reported WinXP (or Intel) behavior during the recent ffdshow changes, but I assume it will work pretty much the same. Last edited by Ger; 13th March 2011 at 17:20. |

I thought I was using the latest FFDShow (beta 7 r3154). That's what it says is the current version on the ffdhow-tryouts page.
I just got a new version (r3771). It does indeed output NV12 now . I wish FFDShow had DXVA though. Without DXVA, my Radeon 5750 clocks up to full 3D clocks! I have to set clock speeds manually if I don't want that. JanWillem32's test build just crashes for me |

That doesnt make much sense. With DXVA, it would use the GPU even more, and less CPU, so the GPU is even more likely to clock up.

Even though I made a custom mode, it shouldn't work since my monitor works only at 60Hz. I'm very confused. |

I noticed with hoborg's mkv sample that "Title" in the information bar (seen above the status bar and below the controls in Aleksoid's screenshot a few posts up) is visible with the internal Matroska splitter when View->Information is checked, but not with LAV Splitter.

Official build / latest official stable, (I can test older to see if they work maybe?)
- Uninstalling and reinstalling Matreshka stuff doesn't fix Haali either. (Are Haali settings somewhere in the registry? - to reset?) {XP Rig} Jan's Latest build which breaks bilinear (PS 2.0) shader, - Haali broken (no fallback renderer...) - just one image in the top right (quarter), copy of that image in the top left (quarter of screen), and the bottom half of the screen is green. {W7x64 rig} Plz Fix! I need to get my XP rig functional as ASAP - it is supposed to be my living room media center for SD and 720p playback.

MPEG2? No one does DXVA MPEG2 apart from commercial apps. The MPC HC one doesn't work with HD5000 series. Only HD6000 and up.
It's a dumb choice. The card goes to predefined clocks of 400/900 for GPU/Memory when DXVA is in use regardless of the workload. If you edit the card's BIOS you can change it to any value. Without DXVA it clocks up for performance reasons I guess. |

My guess is that there is something wrong with the file. If i still had installed all tools, i'd try EAC3to to rebuild the DTS, and use mkvtoolnix to extract the raw video/subtitles. Then i'd rebuild the whole MKV without using header compression to be sure. |

The strange thing is, there is no problem if system default EVR renderer is in use.

But his changes still need another thread. I just discovered another build (BE mod) by bobdynlan, Leo1000. It also should be in a separated thread. The same for xhmikosr's builds. There are builds everywhere but no organisation. Difficult for users and developers... |

Don't blame the software if you have faulty hardware.
