I have rugrats dvds but there is a lot of ghosting and some sort of screendoor effect that looks like small diamonds shapes or similar to a canvas. I watched the Itunes version of the show and the frame rate is smoother and without ghosting. Plus Itunes version doesn't have that screendoor effect and has slightly better details too
Here is the comparison between the DVD and the itunes version:
DVD with annoying screen door effect:

I used handbreak to "cut" the VOB file and make the sample and I chose MPEG-2 option as "video codec". I need to mention that I have no idea what I'm doing...
Handbrake messed up the video. You can use DgIndex to open a VOB file and snip out a small section. Download the DgMpgDec package:
Extract DgIndex.exe to a suitable location -- say, your Desktop. Run it. Open one of your VOB files with File -> Open. Use the slider and the mark-in and mark-out tools ([ and ]) to mark a selection. Include medium speed panning shot. Use File -> Save Project And Demux Video. Upload the resulting M2V file. That will be an copy of the original MPEG 2 data from the DVD.

Then press the OK button to return to the main window. I've never seen this fail.
Another program you can try is Mpg2Cut2. Open a VOB, select a section, File -> Save This Clip (as MPG).
Are you trying access the VOB file directly from an encrypted DVD? You have to decrypt to a VIDEO_TS folder first. Then access the VOB from there.
reduce the frame rate to the clearest 12 1/2 frames per second, then double the frame rate back to 25.
But the fluidity does suffer
Fanfilter is documented to help with this interference pattern but it's not well documented.
Here it reduced it a little
Is this a commercial DVD? This quality is poor. Which episode is this?

One way to reduce the residual dot crawl is to downscale the frame width, then scale it back to full width. It doesn't hurt the resolution too much, especially with a little sharpening.
Davexnet is right about the blending -- there's too much to remove it all. Most of the character animation in cartoons is at 12 fps so reducing the frame rate to 12 fps is only a problem for the panning shots (which are at 24 fps). But at normal playback speed the residual blending of 24 fps is much less annoying than the jerky panning of 12 fps.

Attached is a 11.98 fps version for comparison.
It might be possible to detect panning/zooming shots and use 23.976 fps for those and use 11.98 fps with frame doubling for the rest. Off the top of my head I don't know how to do that though.
