Some people are just doing too many things at once.. every video ive tried works with no problem. If you guys see a little + sign on the bottom left hand side of the clip.. simply click that once, wait about 5-10 seconds and you will see the windows(hour glass) or color thigny come up.. then tcpmp will come up. When tcpmp comes up sometimes you need to hit play.. then immediatly click the full screen button. then you will see the movies
