After doing some research on yadif (about 60 seconds after my first reply), Google sent me quickly to this page, and the first interlacing image was my horizontal black lines.... It all fell into place within seconds, and the ignored vf filter was obvious!  (I should have put "crop" and "lavcdeint" in the opposite order, would have been very obvious then.)

Thank you all for your help.  My avi looks great this morning!
