Hi there,

I have been testing various media servers to use with my Panasonic plasma. I have tried serviio and the 1080p mp4 file was so blocky and colours distorted that it was unwatchable. Now i am trying Mezzmo and the picture has cleared up (blockyness gone) - but the stuttering is now the problem. I have tried a few of these videos but stuttering is still present.

I have an ethernet cable connected from my PC to TV and my computer is a 2500k with 16Gb of ram.

This is the FFmpeg file for the videos:

Hi tangerines,

What device profile is assigned to your device in Mezzmo? Go to the Media Devices dialog in Mezzmo to see this. It should be one of the Panasonic Viera device profiles (perhaps try the various Viera device profiles and see if any produce better results). If no success, then send us a set of logs and we'll be able to see what the problem is. Turn on logging (see http://forum.conceiva.com/showthread.php/419-FAQ-How-to-turn-on-diagnostic-logging) and restart your Mezzmo server. Stream one of the MP4 files to your TV and, when it starts stuttering, stop your Mezzmo server and exit Mezzmo. Zip up all the logs and send them to us at support [at] conceiva [dot] com.

Hi,
I was using the panasonic viera 2011 profile and have tried a few from the list all with the same result.

I have just sent you my log files.

Thanks
