Explain de-interlacing

[Ext User(Barrabas)]

I've never had experience with a high end video display
using de-interlacing. I've been very confused with display
issues I'm getting. I think, but not entirely sure that the issues
are normal with various DVDs when using de-interlacing.

Material with a video history and with 'automatic' set in
WinDVD, and 'cinema enhancement' off, display
a line about two thirds down the screen. Above it
the images are very crisp, almost too much so, and there
is ghosting with movement. Below the line it just looks ordinary.

I switch to 'force weave' and the crispness goes away and the
image looks a lot more even.
Or, with 'automatic' on de-interlacing, I switch on 'cinema enhancement'
and the image evens out, but I don't prefer it. What on earth is
'cinema enhancement' in WinDVD doing anyway? It is on the 'color'
panel, so I don't understand what is going on.

Also, movements can get a bit jerky, stopping and starting
the player sometimes helps, or switching from 'force weave'
back to 'automatic' and back to 'force weave' again can make a
difference.

Thanks for that. But I still can't find anything on
why I get a difference two thirds down the screen.
For some reason I don't get full screen with the problem
video material.
I've spent hours wondering about this and trying different things.
I feel now that I can set a DVD okay.
If in doubt I can just switch on 'cinema enhancement' which
seems to smooth out everything.
I'm not sure if 'force weave' actually means no de-interlacing.
WinDVD gives the impression that it is a form of de-interlacing.
Basically, with 'cinema enhancement' off, preferred.
If the material has a video 'history' (some material was probably
made using some kind of HDTV, it might be further complicated
by 'filmic' effects) then I switch to 'force weave' and the line goes away.
If I get the stiff motion, I can try stopping and starting the video, or
switching to
'auto' and back again.
Good film material, such as Star Wars Episode III, I may not need to
do anything, but if motion gets jerky, repeat as above.
