I have a Panasonic Lumix camera that outputs 720p Video Files in .MOV format. I have been having difficulty in transcoding it to ANY filetype/container combo. The video and audio always begin in sync, but the audio slowly becomes a lagged version of the original video. After a few min, the audio is seconds behind the video.

I have reinstalled and reset the program countless times, not sure what to do... Any Help? Any Ideas?

Thanks a Bunchj!
