Which is why I am slightly against this patch:
Afaict, on DVB-T (SD), all material is signalled as being
interlaced, although all movies and series are progressive
(because 24Hz stretched and "interlaced" to 50Hz does not
produce visible fields).
I suspect who works with interlaced material knows it
and can set the scaling correctly.
Unrelated: Is a filter possible that detects by
inspection if frames are interlaced?
