Yes, this is the only correct way to store interlaced video in 4:2:0
format. Unfortunately it's displayed totally wrong, but that's life...

Once you have interlaced 4:2:0 video like this, you can display it
properly (still interlaced) with -vf ilpack. And of course it's ready
for deinterlacing or inverse telecine.
Interlaced video is such a mess... :(

What format are you recording it in? Could you tell me the command
lines that gave you the different results?
