well, I have one batt char

well, I have one batt charging while the other is in the cam. Then I change them when necessary during an event. So I guess I do "turn it completely off" or whatever. Rats! I can’t take this problem, it is really screwing things up for my editing. Do you ever have to change a batt during the middle of your tape at an event? Or do you wait for the end of the tape and then go ahead and switch the batts before this can present said problem???
