Firmware Update (Version 126.96.36.199) fixes a phenomenon in which the audio and
video get recorded out of sync when shooting movies with the image quality
set to high definition (1280x720 pixels).
This phenomenon occurs gradually from the start of recording and becomes
more noticeable as the recording time gets longer.
* The longest HD movies this model can record at one time are approximately
10 minutes in length. This phenomenon occurs only when the image quality is set
to HD; it does not occur in other settings (640x480 pixels or 320x240 pixels).
