That's what I thought :)
Mild settings for the various filters will, I believe, help a lot.

It will preserve the interlacing. Feed progressive data into
the denoiser and out comes progressive data, feed interlaced
data in and out comes interlaced data.

Hmmm, it's probably just missing from the manpage. The usage()
statement (just type yuvdenoise with either no arguments or with
-h) should have the correct options.

A far better choice would be to upgrade to the CVS version.
Seriously - that will fix the split problem you're facing as
well as a few other bugs. Also, the -N option takes an argument
with the newer version (the default in the old version
corresponds to -N 1.5 which is fairly aggressive, I've found that
1.0 is a good choice).
Before you encode again (and run into the 2GB limit again) check
out and build the CVS version. Many improvements, some of which
could be quite useful in your current project.
Oh, are you using the smilutils or some other method to convert
the DV data to YUV4MPEG2? If you're using the smilutils there is
a quality improvement to be obtained by using ffmpeg's DV
decoder instead of libdv's.
