For 1080i output, Bob 2x should give the best results of all - better
than any other deinterlacer, because with 1080i output, you don't
want any processing of the interlaces, you just want them passed
out in sync. Having said that, I have no idea how you are always
getting them in sync. I'd expect half the time that you'd get the
interlaces being displayed spatially reversed. Perhaps nVidia
have a trick to keep them in sync.
