Shooting on the XL1 then playing back and capturing on a Samsung SCD23. Video is fine but audio squeals on playback. I'm capturing to iMovie HD6 on an Intel iMac via firewire. If I use the "filter audio" in iMovie setting it chops up the audio badly (trying to filter the squeals). If no audio filtering, it squeals during playback, but once captured you can run the clip in iMovie and the squeal is gone.

FYI, no problems of any kind playing back on the XL1 (I want to use the older Samsung to save the XL1 heads).

I'm concerned that the squealing is indicating some larger problem, and in any event I'm sure it's somehow degrading the audio (I have not yet done extensive A/B testing of clips captured from the XL1 and the Samsung to compare).

Anyone have any thoughts?
