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.
