Audio Sync with Interlaced converted to progressive video

[JSmooth]

Greetings. Please someone offer some advice because I am feeling really stupid right now.

Here's what I got. I have an interlaced (true 29.76) source. I use DVD2AVI with FF turned off to create the project and then a decomb filter to server it to CCE.

I end up with a beautiful mpv which is ready for pulldown. Create mpa and I add this to Maestro. It plays fine.

The audio is the problem. I realized that having the video go from 29.76 to 23.976 FPS would require some work on the audio. Here is what I tried:

#1: Took the AC3 file from DVD2AVI and used AC3 Delay Corrector to remove a -33ms delay. Then used BESweet to convert from 29.76 to 23.976 (preset).

result: This created a synced audio package BUT the audio was s..l..o..w.. (actors didn't sound right, etc)

#2: Read about using FF on with DVD2AVI to create audio which made sense so I tried that. Used the AC3 Delay Corrector to fix delay as above.

result: Audio sounded right but sync was WAY off and got worse as video went on.

I feel stupid because I did a search of everything I could think of and everywhere no one mentions how to get the audio back in sync (like everyone is born knowing this). I would appreciate any help or thoughts you may have.

Thanks for your help and, if you are in America, Happy Turkey Day!

OK, I don't understand why this works but it does.

I used the original MPV (non - pulldown) from CCE along with the original AC3 (run through the ac3 delay corrector only) and this worked.

What I want to know is why??

Here is how I thought it worked.

1. Interlaced was saved as 29.76 FPS (audio the same) and decomb would remove the interlacing and convert to 23.976 FPS which would then require pulldown.

Am I wrong? Am I a pathetic loser?? Please one of you incredible experts explain why this works.

Thank you!
