You definitely cannot just eliminate interlaced frames. You'll reduce
your movie to a horrible choppy 18fps if you do that, with large 1/10
second jumps every 3 frames. I don't know why vo_jpeg is incomplatibe
with the colorspace (you'd need to send FULL output) but you can try
-vf detc,scale to convert.
