HV40 Dubbing (i.e., printing, recording back to camera, etc.) issue
 

Problem: noise, dropouts and distortion in dubbing back to tape

Situation: I edit with Pinnacle Studio 12, save the project as MPEG 2, and dub the HD back to the tape in the camera. Now, without burning a Blueray disc, I can show the project on my plasma screen TV by connecting the HV40 via HDMI.

Ordinarily my HV40 produces no mechanical noise at all, with or without the DM-50 external mic.

However, in dubbing back to tape, weird pulsating mechanical sounds occur from time to time. There are audio dropouts--especially in areas where I have moved audio tracks around in the editing. When I redub the same project, the sound problems are never in the same place.

The video is perfect. The vid and audio is perfect on the NLE preview. Vid and audio is perfect when uploaded in HD to Vimeo.

The problem only occurs in dubbing. Any ideas?
