Thanks very much for the reply. You explain the problem very well and I know understand why what I want is very difficult to get. I tried yuvdenoise -I, to just do the deinterlace as it says in my man page, but that option no longer seems to be available, as yuvdenoise prints the usage instructions when I use it.
