Below is a post from the thread "New deinterlacer for perfect image
quality when using an interlaced display, mode that matches the
source" I just thought I'd repost it under a different title because
the original title gave the impression that use of the deinterlacer
was only for interlaced displays. This should give improved
quality on any TV with good 1080i support.
