I see. And 0.19 did not look into the video headers?

So, it's the fault of the channels or the provider.

In that case, it would be extremely helpful to have a setting to force 
this always to "interlaced" (for 0.20 fixes branch).

BTW, what's the negative effect, if I set a progressive recording to 
video scan "interlaced"?
I can see no negative effect here, so maybe this means all my recordings 
really are interlaced, but some are wrongly marked in the video headers?

Thanks!
