Use this, i encoded Matrix reloaded as MPG2 with it and it was almost perfect. It's the V4 without undot.
Code:
AviSource("C:/m.avi", false)
BlindPP(Cpu=4)
Blockbuster(method="noise",detail_min=1,detail_max=8,variance=0.5,seed=1)
Convolution3D(1, 6, 12, 6, 8, 2.8, 0)
GripCrop(352, 240, overscan=1, source_anamorphic=false, dest_anamorphic=true)
GripSize(resizer="BicubicResize")
TemporalSoften(2,7,7,3,2)
DCTFilter(1,1,1,1,1,1,0.5,0)
GripBorders()
[/code]

You could change BicubicResize to Lanczos for smaller movies. I don't know what else you should do, i got a cq of 62.34 for matrix reloaded with that, so you should be able to get a CQ around 75

Use the exact same script as ever but use CQ_VBR insteed of CQ.
(except for high action movie as it seems that CQ_VBR has some problems with them).
Do not change blockbuster parameters like suggested by muahli. It's way too much ! The more the variance, the more noise you add, and the more the denoising filters that follow will let in the picture !
The only thing I change according to the length of my source is the MAX bitrate : I use 64-2300 everytime and reduce it down to 1800 if the movie is very long (and even to 1300 for making extra long KVCD near 2h40min).

Thanx Guys
@ Dialhot
Do you still use 2300 max if the resolution is 352x240,also how do i go about using cq vbr,(prediction and stuff)Do i just use cqmatic and pick the cqvbr option instead and thats it.
Thanx again

use 1800 as max bitrate. Yes, use CQMatic.
and when you're using CQ_VBR don't be surprised if the value is only 25 or something, that's how it's supposed to be

I have a bunch of div3's which are vcd quality, i.e. low res and low bitrate. According to GSpot, the bitrate comes out at around 400-600 kbps, depending on the source. With that being said, what kind of changes should I make to the min/max bitrate in tmpgenc? I have 13 of these files which I wanted to put onto a DVDR... I sometimes find prediction with this number of files a bit cumbersome, so I usually just set CQ to 90 to ensure I'm not losing any quality from these low quality source files. Any comments on this? What if I were doing CQ_VBR, what should I set that at?
EDIT: oops, I lied. When I load these files in Moviestacker, it reports an the average video stream bitrate is ~1800kbps (min1200, max2600).... so with that being said, should I just leave min/max at 300/2500? Also Dialhot, do you agree that we should be using V4 script without undot?

You can set them on CQ80. You won't see any difference and you will save lot of space.

The scale is completly different. CQ70 is near CQ_VBR17. So I guess that CQ80 is somewhere arround CQ_VBR22-25.

All depends on the length, as told before (and the action in the scene of course).

I do NOT agree at all !
You can use Bicubic wihtout Undot as some report they like it (that I not agree when the source is a divx -> too soft) but V4 is V4. That means Lanczos + Undot.

yeah, when i convert dvd-rips to 352x240 KVCD, lanczos+undot takes away alot of the mosquito noise .
