Here were a lot to sort out:

The dvd-wide-ffmpeg+mpeg2enc.m2v from here is also scaled or streched too high in vertical direction.

may be add "expand" filter after crop, so image dimensions will be back to dvd standard?



VLC deinterlaced on playback  (keyboard D) on interlaced m2v gives better quality.



In comparision the ffmpeg command line I have used is:
ffmpeg  -i dv01.dv -f dvd -target pal-dvd -aspect 16:9 -vb 8000k -mbd rd -trellis 1 -cmp 0 -subcmp 2 -vf crop=iw-0-0:ih-106-65:0:
which results in progressive and DAR 16:9, but still not so good edge quality

May be "progressive" here is error, and ffmpeg still encodes interlaced-as-progressive, so VLC for example does not enable deinterlacer at playback automatically?

VLC Deinterlaced ON playback of Progressive  dvd-wide-dv01.mpg results in more coarced jagged or saw-toothed round edges


Have you tried to add interlaced flags manually to ffmpeg's command line?
-flags +ilme+ildct  gives interlaced bff

Yeah, I just suspect ffmpeg was defaulting to progressive flags in stream and progressive setting for mpeg2 encoder  WITHOUT automatically inserting deinterlacer, so result was plainly wrong. 

Metadata copy by default was apparently fixed in 4.4, yet interlace may remain corner case ...

I hope this sum up of the 4 variants I get from Cin DVD creating, using the current unpatched version:

Input file: PAL DV interlaced 4:3
Output DVD cropped to 16x9

The dvd folder file names below are else descriptive

Deinterlaced checked (di):

1) mediainfo ./dvd_wide_cin_di-ffmpeg_20230608-184940/dvd.mpg | grep Scan
Scan type                                : Progressive

2) mediainfo ./dvd_wide_cin_di_mpeg2enc_20230608-201519/dvd.mpg | grep Scan
Scan type                                : Interlaced
Scan order                               : Top Field First


Non deinterlaced (unchecked):

3) mediainfo ./dvd_wide_cin_ffmpeg_20230608-203740/dvd.mpg | grep Scan
Scan type                                : Progressive

4) mediainfo ./dvd_wide_cin_mpeg2enc_20230608-191936/dvd.mpg | grep Scan
Scan type                                : Interlaced
Scan order                               : Top Field First

Obviously 2) and 3) are wrong
Are they fixed in the patched version?


5) Which de-interlace filters are used in CinGG with mpeg2enc and ffmpeg?

I.e some users claims that Bwdif is better than Yadif for ffmpeg.
