EVR renderer in MP not as good as in WMP (1 Viewer)

[alanwww1]

I tested several HW now with all kind of settings and in all case i realized that playing back the videos in MP using EVR has significantly worse quality than when i play it in WMP.

For example:

- Nvidia 8200: ocasional AV sync problems with high bitrate files. No problem with WMP or MPC
- Ati 4550 significant stutter at 50p refresh rate. No problem with WMP or MPC
- Intel G45 micro stutter at 50p refresh rate. No problem with WMP or MPC
- Checking the filtergraphs with graphedit showing 0 fps when playing or sometimes sime very high value. 25fps with WMP or MPC.
- EVR filter has 3 pins compared to WMP's one pin.

I read throug a lot of topics here on this forum with similar problems and i think that the implementation of the EVR renderer in MP is not correct.

What is your oppinion ?

I would just tlove to have stutter free playback with 50p refresh rate, because my videos are mostly in PAL.

Hi,

I agree with all the above. I have to add that my biggest worries are in regards of Picture Quality.

I've tried several combinations of codecs, settings, colorspaces... and the result is always the same:
Comparing the same video, played within MP or played with WMP, the PQ is always much better in WMP.
In all cases I've used graphedit to check the codec chain is the same.

It's really annoying because the PQ is noticeable worse, and I can't find a fix... And, I must say, I have the feeling (can't check at the moment) that is even worse after RC3. The most visible defect for me is an artifact with bright reds (pinks and oranges a bit too) consisting in kind of vertical stripes.

How is it possible? Why is MP consistently displaying worse picture than WMP using the same codecs???

I am pretty sure that MP has a wrong EVR implementation. I also had success with Media Player Classic which also uses EVR.

I think it would be the best to write a bug report, i just want to make sure that it is not only my problem.
