The playback chain is exactly the same in both cases: MPC-HC + Haali for mkv splitting + LAV filters for video and audio decoding:
- when using EVR as renderer, the flow of the video is smooth, although a little blurry
- when using madVR, the image is crisp, the flow is smooth until it suddenly jitters a bit, then smooth again, then it jitters again

This is very easy to reproduce with any 23.976fps mkv, on the movie scrolling credits, I believe.
This is because 24 doesn't fit into 60. It's not possible to have smooth film playback at 60Hz without using interpolation, it needs to be a multiple of 24.

It's nothing to do with madVR.

I'm surprised your i950 is at @4.5Ghz still 100%.
Can you turn on hyperthreading to test ?
Using my i970 (6+6 cores) I have < 10% load on decoding h264 1080p60 with software lav decoder.
The benchmark says 360 fps average on same h264 1080p60..
This is all with hyperthreading on and put the number of threads on 12 in LAV-video.

i970@3.6 / Rampage III extreme / 24GB DDR3@2000Mhz / GTX 570 (very similar as yours )

It should be easy to handle 24fps on 60Hz monitor

suppose 2 frames from the 24fps movie : 1 2
for displaying on 60 Hz we need 5 frames for the 2 frames above. (60/24 *2 = 5)

going like this :
1 1 2 2 is for 48 Hz monitor
1 1 X 2 2 where X is blending frame 1 en 2, for 60 Hz monitor.

This should give fluent playback from 24 fps movie content on a 60 Hz monitor.
I hope Madshi will find some time to implement this in MadVR.

PS: for 23.976 and similar content one could use Reclock to speed up to 24 fps

I believe madshi has mentioned that being on his things to do list. But a simple blending doesn't look very good. You would get smooth (well smoother) motion but you would end up with artifacts from the blending.

MPC hard crashes on DVD menus...the cursor will show the spinning time-out animation, menu music stops and the program will crash shortly after. I don't know if this is an MPC or madvr problem or how I can help solve it. I'm using ffdshow as the mpeg2 decoder, a GT240 with 275.33 drivers and Windows 7 32-bit

This is so frustrating, I can't even tell you the unimaginable amount of times it happens...8 out of 10?

I think I've had this problem for a while now, but it seemed intermittent and I didn't really care that much. Just recently I decided to check it out, and narrowed it down to it happening the first skip after a refresh rate change. After it freezes and you close, it doesn't happen until after you play the next file with a different refresh rate. Using D3D11 fixes it completely, but it has its own problems.

Something similar happens to me with multiple files during the change
I tried clean install of everything but still happens from time to time.
Win7 64bit Mpc,madVR,lav filters,ffdshow raw video filter(for svp) and ati card(catalyst 11.11 and 11.12 involved).

A simple test using EVR, shows that this renderer seems to manage smooth playback even in these conditions.

Therefore, there must be something that Microsoft's renderer does, which gives that smooth flow of the video, without micro-stutters.

It's not for my main machine, it's for my parents' HTPC with a low-end processor. Sorry for the confusion.

The only way without using any kind of motion interpolation, would be to use frame blending as mentioned above. This is at opposition with the goal of madVR, which is the highest quality video playback.

But i think madshi said that playing 24p in 60hz using madvr isn't as smooth as evr, that it's on his todo list

so the problem should be with no matching refresh rates

You said ask a few months later back in April, so here we go

Any chance we could get a few additions to the keyboard shortcuts?

Also you make mention of them becoming adjustable in a future version which would be nice to see, thanks.

Adjustable shortcuts for deinterlacing and IVTC mode would be very nice, especially until telecined material can be auto-detected.

I was also thinking it would be nice to automatically switch deinterlacing on when switching to film mode (CTRL+ALT+SHIFT+T), fwiw.

use lav video in cuvid mode, but force it to output rgb32 and use evr cp.
that is what i suggest to anyone who can't use madvr for some reason.

Although, before you do that, you have tried bilinear chroma in madvr?
Also, you can try overclocking the gpu a little.

now i am facing the exact same problem on same 2 videos on an asus laptop having core i5 2.4GHz,4gb ram,windows 7 x64 sp1 & nvidia GT540m 2gb card.madvr 0.80 windowed mode with all default settings & use separate device for presentation off.these 2 videos play fine full screen on laptop 1366*768 screen.however when connected to LG 32" 1080p TV these 2 videos show massive no. of delayed frames & continuous increase in dropped frames with render queue dropping sometimes to 5-6/16 & back buffer queue 0-3/3 while decoder queue & upload queue are full.this problem only happens on 32" 1080p LG TV watching in full screen but these same videos run fine on laptop screen in full screen mode & in a smaller video window on 32" TV.i am using only lav filters & pot player but also tried mpc-hc with its own filters with same result.

16 is a rather big queue, try to manually decrease the size.
Its also possible that the performance just isn't enough if it uses the iGPU instead of the dGPU (i assume its one of those hybrid things). Maybe try forcing the dGPU?
Also try choosing faster algorithms, like bilinear, just to check if thats a cause.

Does this GT540m card really has 2gb dedicated ram (on the card) or is this a typo ? What is the speed of this RAM ? Is it DDR2 , DDR3 or DDR5 ? Can you post the values reported by GPU-Z? (just memory size and Bandwidth should be enough)

@nevcairiel,i used gpu-z & even enabled logging option while video was playing in full screen just to make sure.gpu load never went above 45% & memory usage was ~330mb.i added pot player in nvidia control panel application settings to use nvidia max performance mode & confirmed it again by monitoring gpu usage in gpu-z.

@Pat357,the 2gb ram is dedicated along with 4gb system ram.it is ddr3 with 128bit bus width & 28.8GB/s bandwidth.

edt:tried bilinear too with same result.even turned subtitle animation off but still no change.

these are the 2 videos:

Disable the Auto settings and lower the queue settings (12 should be fine in most set ups). Also increase the back buffer value in fullscreen mode (experiment values between 6-10, 8 also worked on alot of systems). hopefully it works for you.

Feature Request: CPU/GPU usage percentage in OSD instead of having to juggle between video and GPU-Z. Thank you!

EDIT: I just tested both those files. Working flawlessly here even on low end system using the values mentioned. Hope it helps!

will try your suggestion paladin77 later as i don't have access to TV now.btw your msi notebook resolution is not full HD.i can run these videos fine on my laptop 1366*768 screen.i only face problem running these 2 particular videos on a 32" full HD TV in full screen mode & even there i can run these videos fine in a small video window.
