I wonder if it has something to do with the fact that NTSC DV uses
4:1:1 subsampling instead of 4:2:0. Maybe the dvvideo encoder detects
NTSC based on frame height or maybe it needs special options? I
noticed that vf_scale was outputting 4:2:0 which has no hope of
working in NTSC DV devices, but I don't know if this is your problem
or a separate issue..
