I just made a test of 40 minutes capture resulting in 8 files, and I
did not reproduce the problem.

Could be, but from the looks of your footage it looks like the first
frame has an incorrect size resulting in subsequent frames having part
of one frame and part of another. In raw DV, each frame is 120000
(NTSC) or 144000 (PAL) bytes and most tools and libs just seek to a
multiple of that number to get to frame X. I believe it is nearly
impossible for dvgrab to write an incomplete frame. Or, perhaps the
problem is that the lib in question thinks it is PAL when it is really
NTSC or visa-versa due to some corruption in the beginning. Use
'ffmpeg -i the.dv' or mplayer messages to see if it matches what you
are expecting.

What did you use to view it? Try using playdv and ffplay at the
command line in addition to what you have used.
