Hello I just received a Casio EX-S600 as a gift. I made several videos and then downloaded them to my computer. I played them fine on Google's Picasa. I D/L them into Window Media and then upon playback the sound and the video did not match. I went back to Picasa and the same thing happened with the video and the audio not matching. Any suggestions to remedy this problem? Thank you. Sincerely, JJ
