I really, really wanted some video from a memorial service I just attended. I just got a little Optio RS1500, which I used. I was so disappointed to find out that on most (but not all!?) of the video clips, it didn't record the audio. Instead there is a high-pitched, tinny ringing sort of noise all through it -- nothing else. The video part is ok. In a few of the video clips, the audio came through fine. But 3/4 did not work. Some were shot inside, some outside. No common factor.
The 'movie' setting is for 640/30, which according to the manual, is sufficient for tv screens; I didn't need bigger HD files. While I was back & forth between still & video modes, I don't think I changed any other settings.
Anyone have an idea what the ?!*!@#!! happened? I'm so disappointed.
