That is what I've been expecting from this.
I was playing with yuvdenoise, also with yuvmedianfilter.
I have created few SVCDs, basicaly with something like:
...| yuvdenoise -F | yuvmedianfilter | mpeg2enc ...
also with yuvscaler somewhere, of course.
So after denoise -F it was progressive stream.

When I changed my scripts for a DVD output, I chose to use interlaced 
frames.
So, now I'm using it without -F in denoise step and with mpeg2enc -I 1
I think, it looks better on my TV.
Maybe, the interlaced stream in combitation with high -q causes
this strange result in mplex bitrate report?

BTW: my very first DVD was created by Sonic MyDVD software, because
it was bundled with HW.  This SW has no options for changing nothing and
it is very easy to use.
It creates mpeg which is interlaced and bitrate is about 7500kbit/s.
It looks like mpeg created from mjpegtools without denoise and median,
only by basic lav2yuv | mpeg2enc -I 1 -f 8 -b 7500 ...

So I believe that this first DVD was also last DVD created on win$$.
