Hallo

That is not correct, lavtrans puts out both fields in one file after
each other. But many programms are not able to let you select the next
file. But you could split them using a Hex editor.

mkdir pnm 
lav2yuv -f 40 video.avi | y4mtoppm | pnmsplit - pnm/image%d.pnm

Have you alreaddy taken a look at that section in the mjpeg-howto:
Notes about "interlace field order - what can go wrong and how to fix
it" 

There is also your field spliting question answered, with a better
explanation. 

auf hoffentlich bald,
