I have narrowed it down a bit - it only happens with 24p / 23.976 material.
perhaps the TV is unable to process it correctly?
The E5520 does have support for 24P - over HDMI at least, perhaps the DLNA client doesn't?

Anyone knows for sure that their Sony TV processes this material correctly?

Thanks for trying, though
I still lean towards a framerate issue and I'll run some more tests
to see if I can find a way to make this work.

It doesn't matter if I connect the TV by cable to my
gigabit switch or through my wireless 54G bridge.
Exactly the same happens.

Ok, I have tested several other DLNA server software over the weekend to test the M2TS / AVC issues and the result is the
same for all of them - small jerks every second, most visible when panning/scrolling.
Perhaps my TV is the culprit here

No transcoding - we are talking M2TS files natively supported by my E5520 TV. I have played around with the chunk transfer mode, but haven't noticed any change. It looks like a framerate issue. I have tried with lower bitrate MPEG files and they play without issues. DVD ISO's are also played back fl...

When showing M2TS files on my Sony TV i see the picture stuttering - espacially visible when the camera pans or with scrolling text. Maybe a framerate issue? WMS detecs it as 23.976 framerate movies, which i is. But during playback it looks like it plays at a different rate and then has to "cat...
