Hello everyone,
I've been doing quite a bit reading on the forums esp. the past 5 days..:) and now need some guidance.

Anyways, according to Megui, I have a partial interlaced video and it came up with this script:
# Set DAR in encoder to 4 : 3. The following line is for automatic signalling
global MeGUI_darx = 4
global MeGUI_dary = 3
DGDecode_mpeg2source("D:\NEW0304_SCN\VIDEO_TS\VTS_01_1.d2v")
edeintted = last.AssumeTFF().SeparateFields().SelectEven().EEDI2(field=-1)
TDeint(order=1,full=false,edeint=edeintted)
crop( 6, 0, -4, 0)

Spline36Resize(720,480) # Spline36 (Neutral)
mergechroma(blur(1.3)) # Little Noise

However, I am not satisfied with the results as I can still see some combing. So I decided to edit it and came up with my own script:
# Set DAR in encoder to 4 : 3. The following line is for automatic signalling
global MeGUI_darx = 4
global MeGUI_dary = 3
DGDecode_mpeg2source("D:\NEW0304_SCN\VIDEO_TS\VTS_01_1.d2v")
interp = separatefields().selecteven().EEDI2(field=1)
tdeint(order=1,field=1,edeint=interp,mthreshL=1,mthreshC=1)
crop( 6, 0, -4, 0)

Spline36Resize(720,480) # Spline36 (Neutral)
mergechroma(blur(1.3)) # Little Noise

This greatly improved the video as I don't see much combing anymore. However, I am still not satisfied as I think it can be a bit better. Setting a value of 2 or higher for mthreshL/mthreshC would give me motion artifacts which the AP feature in Tdeint did not help. I wonder why is that?

I have uploaded two unprocessed video where I find parts I am especially unhappy with using my edited script:
Video#1(~19megs):http://www.sendspace.com/file/3p2yxy
In this video, with the company "Creave" intro, the lines in the white background seem to be magnified and it stood out more than the unprocessed video. Also, if you look closely at the bricks right under the white fence, you can see the bricks giving off this shimmer, flicker, moving effect which is quite noticeable. Is this normal or is there a way I could fix it cause its really annoying.

Video#2(~8megs):http://www.sendspace.com/file/v96611
In this second video clip, notice the aqua lines that runs from side to side. I don't know what that is called (flickering?) but it looks ugly as well.

Any help would be greatly appreciated because I have been stumped on this for a couple of days now and honestly I don't know where to search in the forums. So, thanks in advance.

I have tried Xvid encoding via VirtualDubMod, target quantizer=2

# Set DAR in encoder to 4 : 3. The following line is for automatic signalling
global MeGUI_darx = 4
global MeGUI_dary = 3
MPEG2Source("M:\Down\VideoDemo2.d2v", cpu=0)
TomsMoComp(1,5,1)
crop( 6, 0, -4, 0)

Spline36Resize(720,480) # Spline36 (Neutral)
mergechroma(blur(1.3)) # Little Noise

VideoDemo2.d2v has both the videos joined to a single file.
Removed the blue line flickering.

TomsMoComp is great and fast but doesn't it have a tendency of producing artifacts. You can especially see this in the company intro in the beginning.

I am sorry, but I don't see any artifact here (yet). So I uploaded my TQ2 sample here: (6,137,856 bytes)

Could you please load it in VirtualDub/VirtualDubMod and tell me which exact frame number do you see the artifacts? Thank you.

check out frame 383 and previous frames before that.

Thank you, now I do see the artifacts :(
I just quickly checked the motion, I guess too quickly checked, sorry.
