1) Mix Emergency Version 3.3.0 (3.3.0.25) 2) OS X Yosemite 10.10.5 3) MacBook Pro (Retina, Mid 2012); 2.6 GHz Intel Core i7; 8 GB 1600 MHz DDR3; Intel HD Graphics 4000 1024 MB Hmmmmm Nick I started thinking and realized I didn't have this problem until I installed the Beta 3.3.0 so just launched my old 3.2.0 and the sample player video is fine. If I accidentally changed a setting in my ME, wouldn't that change carry over to any other version I launched as well? The plot thickens lol
