iMovie HD audio dropouts on video capture

When I capture video from my DV camera to iMovieHD, there are rapid irregular audio dropouts. No problem with the video. Sounds like a loose connection, but can't be. This might have started when I upgraded to iMOvie HD--not sure. I've tried other firewire cables, two cameras, unloading all extra hardware, disks, and software on my Mac min os x, reloading iMovie. A window PC works OK capturing the same video from the same cameras. Any ideas?
 
Are you capturing to a FAT32 (aka MSDOS) formated drive? This may cause problems, as the maximum size file those drives support is 4 GB. What is the model of your camcorders?
 
I tried three different disks: my Mac Mini internal disk, and two external disks formatted for my Mac. Plus, all three disks work OK with video I previously captured. The problem appears to be something that happened recently. Camcorders, which worked previously, are Sony DCR-HC20 and Samsung SCD23. As I noted initially, both camcorders work with Windows PC. Also, I just tried feeding the Sony camera into a stand-alone DVD recorder (used with TV) via firewire, and the audio transfers OK.
 
Here's something interesting. I discovered that I only get the dropouts when I'm playing a tape that was NOT recorded on the camera. (I was trying to capture a miniDV tape recorded by an outfit that transferred my home film movies to tape.) Tapes recorded on my camera still work fine played back on that camera. What's puzzling is that all tapes work fine when played to a Windows PC or a stand-alone DVD recorder. It's only the Mac that has trouble. But I have a workaround for this one-time situation: Capture the tapes on my Windows machine then export the file to my Mac.
