I have set the media device settings up for a Sony KDL Bravia set, the network to 100Mbps, the screen resolution and backed off the transcoding as this works for my setup. But when I come back to it the next day (the machine running Mezzmo is powered down) the settings have resorted back to 1Gbps and high quality transcoding although the Sony KDL is correct identified.

At first I put this down to my error. But it has now done it several times. Any advice?
