Also, if you're having problems - don't hesitate to contact me. Either here, or via e-mail ( support@inklen.com ). I'm always keen to hear about (and try to fix) any playback problems. MixEmergency 3 has had some *huge* changes "under-the-hood", and even though we have a lot of beta testers who have been testing it over the last 6 months, it's often not until it gets released and 100s of users get to try it that we find more subtle issues (such as particular hardware, setups, video encodings, etc that can cause problems).
