Hi Chris,

We did find and fix a bug in Mezzmo v3.3.0.0 that could be causing your slow transcoding speeds. We did have a similar problem with our Viera TVs here. Please upgrade to Mezzmo v3.3.1.0. After upgrading, go to the Media Devices dialog and edit your Panasonic Viera TV. On the Device Settings dialog, go to the Advanced tab and click the Default Settings button. Click OK to save your changes and now try to stream a few files to your TV. Let us know if that is better. Hopefully, there is either no transcoding at all or transcoding is much faster.
