I believe this is backwards. In DV, the bit rate (megabits per second)
is the same at either speed. So, when the tape is moving slower,
the bits have to be closer together. This makes for a less robust recording
at the slower speed.
If everything is working correctly there should be NO diference in picture
quality.
However, tape damage or other tape path issues can reduce the reliability,
and
dropouts may increase. DV has a pretty good system for the correction of
dropouts,
so even then you are not very likely to see the dropouts unless they are
pretty massive.
There have been a few reports of problems playing a tape that was recorded
at the slower speed on a diferent machine than it was recorded on.
