Just wondering what is the best method for using Virtual Dub. Basically have mpeg2 files from the JVC DVD recorder now it needs to be cleaned in Virtual Dub.....

VirtualDub 1.6 MPEG2 edition. Save the MPEG to a
HuffYUV intermediary file, with no changes made. We want to retain proper chroma interlacing. There's an issue currently with
VirtualDub non-MPEG edition improperly mucking up the chroma interlace (but oddly the luma is fine).
Then load that
HuffYUV AVI in the current version 1.9x VirtualDub to take advantage of the past 5 years worth of VirtualDub advancements.
There is some potential that this step is not necessary, but those tests are pending. Better safe than sorry, for now.

1) One of the Problems is the interlacing damage to the video.
AVI is Bottom Field First Correct?
Do u just load in the ripped DVD or convert it to bottom field first?

AVI does not have field order flags. MPEG does.
The device creates the field order. DV is bottom field first. Almost everything else is top field, including every DVD recorder I've ever seen (and that's quite a few!)

Do you do your videos edits before or after you create the AVI?
Is it smart to edit an AVI file or just edit the mpeg2 file, and when is the best time to edit the video?

As per earlier in the post, we'll do it afterwards right now.

2) Going from AVI back to mpeg is causing motion problems. (Could be just something stupid that I am messing up)

This could be due to VirtualDub errors. Or maybe it's just the filters you've used. Or the import/encoding settings when you turned it back into an MPEG. Some filters are only good on progressive (non-interlaced) source. Not all of them say "progressive only", however. Most filters, to be perfectly blunt, have horrible documentation (if any). VirtualDub isn't great, and Avisynth is even worse.

You want the motion to be the same as the source DVD however it is understood heavy filters are been used on the videos...aka Neat Video..

Heavy filtering temporally can affect quality, especially if the filter is treating the video as if it were progressive source.
