Having an issue with a Ali G Season 2 NTSC DVD

The sourse is interlaced, and therefore my first attempt using dvd-rb on this disc resulted in an interlaced output (obviously).

Then I re-tried selecting "DeInterlace With Decomb" under the Options/AVS Expert Options. Yet still resulted in an interlaced output. Later finding out that I needed to have the decomb filter installed first.

I installed filter through dvdrb setup

Location of filter install (by dvdrb)
C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll

rebuilder.ini says
DECOMB=C:\Program Files\AviSynth 2.5\plugins\Decomb521.dll


Ran dvdrb once again(with "DeInterlace With Decomb" still selected) , and yet still my ouput was interlaced.

other details:
I am using CCE SP (2.70) 5pass to encode, stealing 0% from extras.

Am I missing a step or setting? Is there a better/simpler way to de-interlace the video??

As always any help or insight is appreciated.

It is still going to be interlaced. All that filter does in DVD-RB is smooth (blend) it for a little better playback on computer monitors.

On a truly interlaced source you can never actually "deinterlace" unless you are willing to give up part of the picture. That's because there are temporal differences between the fields.

Does DVD-RB do a deinterlace even if I don't do a re-encode on a DVD but just select under options deinterlace with decomb and leave 100%?

thanks

If the disc isn't reencoded, no action (like deinterlacing) can take place.

I still suggest, however, that except in rare and unusual circumstances, deinterlacing is a bad idea.

The picture on the computer is bad and I mainly watch it on computer. But thanks for the fast reply!!!

You might want to make sure deinterlacing is enabled on your software player, and play around with the different modes to see which works best with your source/eyes.

Thanks, wmansir. I did that and the picture did become nicer and "less" interlaced....

Thanks again
