Mixed Video Types in Womble MVW

I didn't think there was much left in the realm of DVD that could stump me, but I'm stumped.

I'm trying to add an 18 second scene back to ADM's Love Actually disc.

ADM's video is a mix of 29.97i and 23.976p video.  So short of re-encoding to full progressive, this needs to be edited with the pulldown flags intact(?)

First I used Mpeg Video Wizard's GOP Fixer on the commercial disc, tested ADM's and it doesn't need fixing.

In MVW I cut and dropped in the scene I wanted to add and done... right?

Playing segments throughout under MVW shows everything to be perfect.  But when I export the streams and remux, the audio is badly out of sync for everything before the point where I edited it.

I normally I don't work in MVW with pulldown video, but it is unavoidable here.  I can't think of a way to fix it, and I don't know any other programs that (nearly) losslessly edit like MVW.

Suggestions?

It does.  Have you tried re-encoding the whole audio?  I can't think of anything else.  It's been years since I used Womble.

Does the end product have to be a DVD?  If not, you could perform an inverse telecine, edit in another program, and use then x264 to recompress.  With decent settings, you probably wouldn't notice any difference in quality.

 I was shooting for DVD.  Maybe running delaycut through the AC3 stream will help.

Edit: Hmm.  No errors found in either audio track.  I could deinterlace ADM's stream and re-encode it, then edit it, but that's starting to be a disproportionate amount of effort for a small gain.

This has my goat though.  I always assume hard interlaced and soft interlaced were treated the same.

You might try VideoReDo.

 I'll take a look.
