Media players and Premiere do not necessarily display you the whole
truth. Open the captured AVI file in VirtualDub and you will see how the
video data _really_ looks like:
<http://www.virtualdub.org/>
(BTW, how _did_ you capture it? What kind of cable did you use? USB?
Firewire? Which program did you use for capturing? When you open the
file in VirtualDub and choose "File" -> "File information...", what does
it say in the codec field?)

Check your project settings. Compare your
1) imported material,
2) project settings,
and 3) export settings with each other.
Are you using the same pixel resolution (frame size in pixels) for all
of these? Are you using the same AVI codec for all of these?

What you're describing is normal interlaced video, as viewed on a
computer screen in raw format. That's nothing to worry about - it's just
the way it should be. See here for more information:

TMPGEnc should accept interlaced video just fine. The DVD format also
fully supports interlaced video. The symptoms you describe could occur,
for example, if the field order ("top field first" / "bottom field
first") is not correctly set up in TMPGEnc or Premiere settings, or if
the video is, at some point during editing or exporting, incorrectly
resized in the vertical direction.
Then again, TMPGEnc usually tries to detect the correct field order
automatically when you import material in it, so I don't believe it is a
TMPGEnc problem. I suspect the problem is with your Premiere project
settings, or Premiere export settings.
In order to test this theory out, try offering TMPGEnc a (short)
captured video clip that you _didn't_ process in Premiere. Burn a DVD
and see if the quality is better that way. If it is, it is clearly a
problem with the settings you're using in Premiere.
