I have to make a correction on my previous statement, the power button still turns off the cam, you have to hold it until the camera goes off. It might take few seconds. Also I noticed that in the menu settings the setting for GMT has disappeared, but the time is correct. Will see when we go back to Standard Daylight Time. One more thing, I'm not been able to get sound on any file that I play on the computer, no matter what program I use. But I'm able to get sound if I use the Registrator Viewer to play the files. Any idea why?
