I think -I together with --encode_fields doesn't make sense at all.
Using -I is to deinterlace, where --encode_fields tells the encoder
that the stream getting in is interlaced and it should keep the
interlace information.
If you deinterlace first, but afterwards tell the encoder that the
data is (and should remain) top-field-first, you will IMHO produce
rubbish.
In other words you push progressive content in, but explicitly tell
the encoder that this stream ist tff.
I am neither very familiar with vcd (pal or ntsc) nor with ffmpeg,
but for my dv->dvd (PAL) transcoding I simply use --encode-fields
b[1] and mpeg2enc respects it and produces a interlaced mpeg2.
[1] Yes, somewhat strange. In spite all other PAL signals are
normaly tff it is bff for DV.
