That's okay. I only just noticed that you had replied. If you want to give yourself a crash course in Avisynth, or use an Avisynth based GUI, you can crop and resize different sections of the same video by different amounts if need be, or apply different filtering to different sections. You can also edit before you encode by selecting just the frames ranges you want to keep. ie
Trim(0, 1457).CropResize(640,480, 16,8,-16,-8, InDAR=15.0/11.0)\
++ Trim(1589, 3652).CropResize(640,480, 24,18,-12,-8, InDAR=15.0/11.0)
I'd recommend MeGUI, as after it indexes and opens the video, it opens a preview and you can manually edit the script it creates and preview the changes, then encode the script when you're happy. Possibly the most important thing is to make sure you keep the original DVDs in case sometime in the future you want to try again with different filtering etc.
The examples in the attached zip file are by no means a suggestion as to what you should do, but intended simply as an example of the sort of thing you can do. I haven't had much experience cleaning up noisy home-made video, so I just added "some de-noising" to the first sample. I'm not even sure the way I denoised before de-interlacing is the correct way to do it. The filtering I added is dog slow, so you might need to create all the encoding jobs, queue them up, and let the computer spend the next week running them.
For both samples I adjusted the picture brightness and gamma a little (I'm not saying that's what you should do), and for the second one I used fast de-interlacing without including noise removal. The x264 Film tuning is used for the first sample and the Grain tuning for the second, and both are de-interlaced to 50fps progressive and encoded at CRF16 with x264. The difference in bitrate is a fair indication of how hard it is to compress all that noise (28.7MB when de-noised, and 156.2MB without de-noising, for 52 seconds of video). The two Avisynth scripts are included in the zip file. You can open them with Notepad.
If you want to give yourself a crash course in Avisynth first, so you can produce something decent, I'm sure a resident Avisynth expert such as jagabo would be able to offer some really clever script ideas to make the rest of us feel silly.
Samples.zip (185MB) Link good for a few weeks. Edit: The upload site I used is a bit crap. After clicking "free download" and getting through the Captcha, right click on the "click to download" button and select "save link as" if left clicking on it just opens ads.

Actually hello_hello using temporaldegrain on the separated fields works well.
When I first looked at this, the video was so poor, I didn't even realize it was interlaced.
You know what they say about assume ...
