I'm trying Mezzmo to stream files to my WD TV Live. It works fine when files are not transcoded, but sometimes very big 1080p video files stutter. So, since my TV screen is only 720p, I set 1280x720 as the maximum video resolution for the device, in order to save some bandwidth, but the resulting file is unwatchable, because the video is full of purple and green vertical lines. How can I solve this problem? The files I need to play are 1080p mkv files, with x264 video tracks.

Thanks.
