JVCHD110 and Sound Devices 722 Audio Drift
 

I know that quite a few people out there are using the Sound Devices 722 for Double Sound with the JVC.

I bought my 722 specifically for this but I am experiencing audio drifting gradually off sync quite quickly. I estimate I am losing about 2 seconds an hour.

At this stage I think the 722 is implicated because I have recorded double sound before with my Metric Halo and it stayed in sync almost precisely even for long pieces.

Is anyone else experiencing this problem with this combination?
