The .NUV is misnamed.  It's just a straight MPEG.

Since it's just an MPEG anyway, there's no reason to demux and remux
it, except as necessary for the DVD format (adding spaces for the NAV
blocks, etc).  The ivtv driver can supposedly spit out a DVD-compliant
stream by setting the stream type to DVD (test_ioctl -c stream_type=10)
but I'm not sure if that has all the necessary stuff in there to just
dump onto a DVD.  You should check the ivtv-devel archives and perhaps
ask there.
