Please tell us (i) device you are streaming to, (ii) the device profile assigned to your device in the Media Devices dialog, (iii) the FFmpeg information for one of the videos that looks poor after transcoding (right-click on the video in Mezzmo and click 'Get FFmpeg Information'), and (iv) any adjustments you have made to Mezzmo related to transcoding or your device streaming.
I'm using a Sony Bravia 2012 (KDL-46HX850) TV and the device appears to be correctly detected by Mezzmo as Sony Bravia KDL (2012 Models). I've done some adjustments to set the BW to 100mbit and then 1gbit and to force the burning of all subtitles because this TV doesn't play subtitle streams. Where can I find the file to edit the ffmpeg options to set it to ultrafast? Here's the file information for the file in question:
