I've noticed that since every OS beyond the original .65 my video camera is very difficult to start and stop recording. The only button you can use to start and stop a video recording is the touch button on the screen. It is just unresponsive. It seems like I have to touch my finger to the button for about 3 seconds and it will highlight blue and then I can click it to initiate or stop the recording. I never had this issue on .65 and it's been the same probelm from .75 on up. I wish you could use the side convenience key to record and stop recording like you can use it to snap a picture. If you can use the convenience key, what am I overlooking to get it to work that way?
