Duplicate frames with HMC150 using Prerecord function?

Anyone else seeing four duplicate frames at the start of clips using the Prerecord function? Doesn't happen every time, but very frequently.

This is causing an audio sync issue when using Neoscene.

OOOOOHHHH.....hmmm...i just recently ended up with one clip that was about 8 frames out of sync and i couldnt imagine why. i use prerecord all the time. to the extent that i forgot about it completely. it might be a case of stopping and then restarting too quickly
 
The initial four frames of a clip using Prerecord are dupes, but the sync appears OK in the m2ts file. Neoscene deletes the duped frames but in turn makes the audio lag by 27 frames.

It's possible to use the video from the Cineform AVI and the audio from the m2ts file by aligning the two at the end of the clip and trimming the initial 27 frames of video, but that's not a workflow anyone wants. Better to turn off Prerecord or do without Neoscene.

I'm seeing this on two cameras, so I'm assuming it's widespread. Be nice if Panasonic could fix via firmware.
