Okay, so I'm posting at myself, but that's fine.  I wanted to give you all an update, and ask for suggestions.

In version 1, I may have used a bit to much post processing in dgdecode.  I think I could have used some deringing, but it's been a while and I'm not sure.

I used Restore24 to get back to 23.976 which uses an internal deinterlacer.

I actually spent a week creating, in pieces, a lossless v2 using yadifmod/nnedi2 with srestore.

The advantages: More modern restoration filter, less dgdecode postprocessing, possibly smoother motion, 10-20% sharper image (thanks to a serious deinterlacer), and a bit less cropping.

The disadvantages: More artifacts including a bunch of mosquito noise (even with denoising), the smoother image is because srestore chose more blurred fields than restore24 (this is most noticeable in animated scenes.)

For a pointless comparison, here are some screenshots. http://www.mediafire.com/?4tsj6g3vejglggj

They don't really mean anything because I only took snaps where the frames were the same.  In most cases different fields were selected so there were no matching screenshots possible.

What might be ideal would be finding a way to disable restore24's internal bobber and using yadifmod/nnedi2 in it's place... but I don't know how much good that would do, even if it's possible.

I think the problem is actually the noise.  If you filter more, the 24fps restoration is more accurate, if you filter less of it, your picture is sharper, but you get more blended fields.

Anyone have a suggestion?  If not I'll just go ahead and release v1.1 (which has the same video/audio as v1).
