Thanks. From the log file I can see that a lot of your videos have very large keyframe distances (during your last set you played some videos that had keyframe distances up to 300 frames apart). I recommend using videos that have keyframes closer together, such as, at maximum, 25-30 frames. I would guess that this is what is causing the freezing issues for you. If you open that log file in a text editor, and then search for the text "Warning: Keyframe distances are large", then you'll find the videos that have been causing you issues. The easiest thing to do would be to re-encode these videos, making sure that they keyframes are set to around 25-30 frames apart. You may have noticed that a little warning icon (with a "!" symbol in it) may come up every-so-often on the main MixEmergency window while you are playing - if you push this, it will open the Messages Window and show you which file is causing you keyframe issues at the time.
