ffmpeg video conversion issue with MOV to MP4

someone gave me some MOV files that will not convert directly to MP4 using FFMPEG.

I tested other MOV files and they converted fine.
(ffmpeg -i car.mov car.mp4 works perfectly)

If I look inside a "normal" MOV file (ffmpeg -i car.mov)  I see this -

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'car.mov':

The problem file "never.mov"  shows a video stream of dvvideo (dvc...
That other video shows a video stream of h264 (which is what I expected).

Any idea why the "never.mov" video has this format?
And how can I convert it to mp4?
