HDV Camcorder not recognized in FCPX/iMovie/Quicktime in Monterey (12.3)

Hi,

Up until a few weeks ago I was able to import HDV video from my Canon HV-20 into FCPX using a Firewire cable on my new MBP M1 Max. This is a setup worked well many times before. But when I tried to import a tape today the camera doesn't show up in FCPX/iMovie/Quicktime anymore.

The only thing that changed (that I can think of) since last time I used it is the version of MacOS. Interestingly, the same camera with the same cable shows up just fine on a different laptop, an older MBP (Intel-based) running Big Sur.

In addition, I can see that the camera is properly recognized on the Firewire bus by MacOS on the M1 Max. It shows up in the System Information application (under Firewire) and on the command line when running:

Just not in any of the video import dialogs.

Since it was working a few weeks ago, it makes me think that something may have broken with one of the latest versions of Monterey.

I wonder if anybody else with an HDV camcorder/deck can confirm if they can see them as an option for importing video on an M1 Mac running the latest version of Monterey (12.3), either in FCPX, iMovie or Quicktime.
