Nm is right. I suggested to discard non-reference pictures and consequently don't display them.
Before discarding of pictures a decoder should care the very particular case when in a single complementary field pair one field is used for reference while another not. Indeed, in such case how the frame can be displayed if one of the two fields is absent.

As usual a removal of non-reference frames causes jerkiness artifacts. Although in case of significant motion or a scene cut the removal several frames is not noticeable.
