I've had my DVX100A for a few months now and have recorded about 20 hours footage so far. Recently I've noticed a little glitch with the record button. On a few occasions it hasn't responded right away and the time code has read 00:00;00. On such occasions I've had to press it a few times (always with the same amount of finger pressure) before it went from PAUSE to REC. Today, another strange thing happened. I had recorded a few minutes on a new tape and then stopped recording for a while. When I tried pressing record again it wouldn't respond and the red empty tape symbol started flashing on the LCD. After a couple more tries, the camera was functioning normally again. Has anyone heard of this problem? Should I be concerned?
