I want to wrap the DV stream from the .dv files into Quicktime MOV (without transcoding) so they can be imported into Premier Pro.  FFMPEG rewraps the stream but when played in Quicktime, VLC, and Premier Pro there are narrow black vertical bars on the left and right edges of the frame.  It looks like the production aperture 720x480 is being displayed instead of the clean aperture 704x480 but that’s just a guess.  Can someone tell me an FFMPEG command that will result in MOV wrapped DV that displays without the vertical borders?

No clue in your case, but a captured DV tape can contain glitches that might interfere.
Watch the DV stream around the part where the re-wrap stopped.
