style="font-size:small">Andrew, after
many, many runs and actual DVD media
creation with these patches in, I am
almost certain that all is working well
and now there is the choice of creating
BFF media. So answer to question of "do
you still get interlaced" is "YES" as far
as I can tell. Here are some of the
results / differences seen when use
"mediainfo":</div>
<div class="gmail_default"
style="font-size:small"><br>

<div class="gmail_default"
style="font-size:small">1) GOP,

GOP, Open/Closed of first frame :
Closed -------------------> Before</div>
<div class="gmail_default"
style="font-size:small"> GOP,
Open/Closed :
Closed -------------------> After is
just this 1 line which makes sense</div>
<div class="gmail_default"
style="font-size:small">2) Scan type is
a little confusing though:</div>
<div class="gmail_default"
style="font-size:small"> Before
-----> it always read Interlaced for
all, whether or not the Deinterlace box
was checked or not</div>
<div class="gmail_default"
style="font-size:small"> After
------> if Deinterlace box is checked,
it reads Interlace</div>
