I am curious as to EXACTLY what you mean by 'non-temporally compressed.'

DV-25 compresses on a frame-by-frame basis; succeeding or preceeding
frames do not have any effect on the compression provided a given
frame.

mpeg2 compress succeeding and proceeding frames by detecting elements
that change when compared to a reference frame. In this way reference
frames effect the compression given preceeding and/or succeeding
frames.

Because changes over time alter the compression, mpeg2 is said to be
"temporally compressed." DV-25 doesn't have this feature, so it is
"non-temporally compressed."
