Nasty Artifacts when playing MKV files via PS3

First of all i would like to thank the author for the time and effort he put into this brilliant piece of software!

So... Huge Thanks!!!!

My problem (and i've tried 0.52 and 0.6) is that almost any MKV file i am trying to play on my PS3 has real bad artifacts around moving objects, especially when the scene changes.

Info of a faulty file:

I am running a 4GB Core i5 Machine with Windows 7 on it.

Anything i could try ?

[Cerberus]

this is likely to be down to your network not being able to handle the stream or broken file rather than serviio issue.

I doubt it because
a. it happens on almost all the MKV files i have
b. PS3 Media Server can handle the network traffic just fine so i don't see a reason why serviio woudn't + i use a 1GB wired connection between the PS3 the router and the streaming computer

[Cerberus]

then when are at broken file, as there is soething in it that FFmpeg doesnt like and taht why u get artifacts.

Ok, so how do i diagnose it ? Is there a way to fix it ?

thanks for the responses btw

reencode them, also check that header compression wasnt used when they were encoded as this causes all sort of problems.

could you elaborate a bit ?

What is your TV model? do you have some "Motionflow" option activated?

My TV model is Panasonic V20 plasma, but i am using the PS3 as the DLNA receiver.

My TV model is Panasonic V20 plasma, but i am using the PS3 as the DLNA receiver.

Do you have some "Motionflow" or "Motion Smoother" option enabled on your Pana?
And do you confirm that when using PS3 Media Server with the same device : PS3+Panasonic V20, you don't have artifacts?

No, those options aren't enabled
And yes, i confirm that using PS3 Media Server + My Panasonic TV there aren't any artifacts. The problem has to be with the mkv decoder of Serviio.

So this file must be re-muxed into MPEG2 Transport Stream, video and audio codecs must be copied.
Enable detailed logging (see signature) and check the ffmpeg command line used to deliver this stream.

Could you also check the PS3 Media Server logging, probably this file is transcoded into MPEG2 video, so there were no artifacts.

Just to confirm, you want me to enable detail logging and play the file right ?
Or am i to remux (not sure how) the file into MPEG2 first and then try to play it ?

[Illico]

Just to confirm, you want me to enable detail logging and play the file right ?

Yes,
-First, just find in log the ffmpeg command line used by serviio to transcode this file (so enable detailed logging and start the file).
-Then try locally the same command line in windows terminal, an add the resulting output file to the library and see if result is the same.
-And that could be fine to compare with the PS3 Media Server encoder command line.
