animated film quality coming from mpg to dvd

The image quality on my animated films is very stuttery on the films I'm burning from mpg files that originated as raw avi files transferred from digibeta source. You can see the interlaced image as often as the solid image, it seems. It's disturbing to view. We checked it on the computer and on a dvd player.
I used Adobe Premiere to make the mpgs because Sony Vegas Movie Studio couldn't see the raw avi video. I made intermediate avis within Premiere before I made the mpgs, so there are probably render issues here.
The image quality on my animated films that came directly from vhs to avi files via the Sony basic program click to dvd do not have any stutter. I have been burning to Sony dvd-r discs set at 4 x. Any ideas on what could be causing this? The process of checking is so slow since I have to render and burn each time, as I'm sure you all know well.

When dealing with any material that was telecined (upconverted from 24 fps or, in the case of animation, even a lower frame rate, up to 29.97 NTSC or 25 fps PAL), you generally want to do an Inverse Telecine (IVTC) before encoding, otherwise your encoder goest nuts processing some frames that are duplicated (and there will be a lot of these with an animation).

Even worse, depending on how your video was captured, the telecine flag may be set, telling the encoder to do another pulldown.

Here's one of many links that describe some of the issues:

I really appreciate the information you've provided, but now am not sure now how I can proceed, without buying a lot of one use only software. Here's the chain my animation has followed
1" master long ago from 35mm materials.
Digibeta from 1" master this year (vhs copies of this Digibeta look excellent). Digibeta created at a top video production house.
Raw avi on a Maxtor drive of Digibeta, at low price outfit that seemed to know what they're doing.
Copies of Raw avi on my Sony Vaio hard drive, which I'm working with.
I see the interlacing on the raw avi when I scrub through it in Adobe Premiere. Neither Sony Vegas movie studio nor Sony DVD Architect Studio can even show an image from the raw avi. Can you think of any way I could get a decent image on dvd with the situation I have here? Thanks for any thoughts.

hmm, found de-interlace command hidden away in Adobe Premiere- cool- seems to make a big difference in first tests I've done.

I have scripting abilities (javascript, flash MX), and scripting doesn't scare me off- so do you think if I download VirtualDubMod and Avi Synth filters Decomb package, that I could get my act together? Or do I need to go back to a video house to get my source materials in shape?
