Software decoding video and audio on my i7 only takes about 3% of the CPU when running madVR, i cant understand the need for DXVA from an i7 POV anyway. And i got an i7 + 5770 in a HTPC case (which is perfectly possible).
The thing im amazed about is how many people still run ancient hardware that needs DXVA and are willing to pay for PQ by doing DXVA scaling, when PC parts these days are so cheap.. |

edit: Nevermind haha, found a tool that changes it with a hotkey. Changing the refresh rate while in fullscreen doesn't cause this. However, if madVR's changer is activated, it will quickly revert the change to whatever madVR wants it to be, which causes the icon to show up again, without even leaving fullscreen.

This is not a joke! I have been used several recent-yeared Intel graphics platform like HD2000, HD3000. All of them are much slower than nVidia ION or AMD/ATI HD5450m, and the Intel graphics driver is much less features. It also has somewhat unstable driver stability on video playback functions. My HTPC is also an aged hardware. But it is still the fastest one among all my own. C2D E8400@3.6G + MSI Lightning GTX260+ (GT200, 216SP, 1792MB). With the madVR Luma Lanczos3 + Anti-ring + CUVID, I found the GTX260+ could be overloaded for H.264 1280x720 & MPEG2 HDTV 1440x1080 / 1920x1080 contents displayed at 1920x1080. I need to turn off Luma's anti-ring, or use SW MPEG-2 decoding + processing. But SW MPEG-2 decoding sacrifices some MPEG-2 quality enhancement by this nVidia GPU processing. With madVR previously, it is only available by using CUVID to let GPU process the entire decoding + post-processing (de-ring + de-blocking deinterlacing) which the video image needs to be moved twice between GPU RAM and MB RAM. Since DXVA input pin is supported in madVR 0.85.x now, the same GPU processing quality can be obtained with reduced GPU loading and I can use Luma Lanczos3 Anti-Ring with most 1280x720, 1440x1080 contents on this GPU. Even the nVidia old GPU (VP1, VP2 engine) and AMD/ATI HD5xxx (or older series) and Intel old GPU (?) which are not capable of DXVA2 MPEG2_VLD, but only MPEG2_IDCT / MC, it is still able to take advantage of either quality post-processing or performance-optimized MPEG2 video decoding. For such HW, use Microsoft DTV-DVD Video Decoder to handle MPEG2 video and output decoded image to madVR via DXVA2 path. Last edited by pie1394; 30th November 2012 at 14:51. |

Yet all video menus and contents are actually PAL 720x576 16:9. I did the verification by playing all individual .vob files and all of them get switched to 1920x1080i25 mode. madVR - log[DVD_PAL].rar |

@Madshi, don't know if already mentioned but deinterlacing features via shortcut keys are broken.
Regarding the dvd fps issue, correct me if I'm wrong, MadVR is the last in the chain, so if FFdshow Raw Filter shows me the correct result and also Reclock this means that Lav video is telling something wrong to MadVR or could it be Raw Filter out? |

I don't know which upstream filter is reponsible for the wrong FPS information. You can look at the pin connection information in MPC-HC. The key information is: "AvgTimePerFrame: 417083". You can calculate the FPS from this by doing: "fps = 10000000 / AvgTimePerFrame". |

This is really strange. I am too using a GTX 260 in an old system having Pentium D Processor. I also use CUDA for decoding videos. My system is able to handle all kinds of commercially available content with the following settings: chroma upscaling - Jinc 4 taps AR, image upscaling - Jinc 3 taps AR and image downscaling - Catmull Rom AR with Linear Light. My system fails (drop frames) only while playing 1080p 60 fps videos, 4k videos etc. For these files also, it is the hardware decoder which is not able to cope up. Do you have Antialiasing and Anisotropic filtering settings in NVIDIA Control Panel not set to "use 3D Application setting"?

Most sources are 24,25 or 30fps. Most ouput are 1080p. And plenty of GPU can handle Jinc3 easily in these cases. My HD5770 for example, despite not being a "powerful" video card. Another example: It isn't in comparative anymore, but I can play Crysis 2 without problems with good quality. But if you take extreme scenarios, you will find 720p 96fps sources, for 1440p output with 3 sharpening filters, 2 denoise, etc. |

Sorry, I cannot reproduce it anymore, but last time it showed while playing a dvd (with Lav Video Decoder set to NVIDIA CUVID HW decoding) and trying to manually (via shortcuts keys) toggle either deinterlacing on/off or change the deinterlacing content type, an OSD message appeared that it couldn't be done because... (don't remember...)
