I can't notice differences at playback with VLC and FFplay (other than 
16:9 vs 4:3 format as usual). And both visually with good qualities in 
my eyes.

Cingg Set Format Interlace Mode: Not interlaced
did the trick and both hdv and hd could be rendered
FFprobe reported it is pgogressiv, while native FFmpeg transcoding still 
say interlaced.
