Audio sync issues converting DivX with huge audio preload

[DRP]

I need some advice or help in converting a DivX video with a large audio track preload figure to SVCD. Getting the audio to sync up properly with the video is the only issue.

VDub reports an audio preload of 1.41 seconds which is the largest I've ever seen. I have tried extracting the audio with GoldWave and then inserting 1.41 seconds of silence to the beginning, but this just shifted it too far back and the audio became late instead of early.

I have also tried using the AVI as source for both video and audio and letting TMPGEnc do the resampling, but this didn't work either. Finally I tried the following AVS script...

AVISource("C:\Documents and Settings\Temp\filename.avi")
ConvertToYUY2()
ConvertFPS(25)
EnsureVBRMP3Sync()
ConvertToRGB24()

...but this results in audio being too early as well. Finally I have tried using both DivX 5.1.1 and XviD 1.0 Final as the decoder (the file is actually a DivX v3 encode) but this made no difference. Any other ideas? The file does play fine in MPC & PowerDVD with no audio sync problems.

I would decompress the avi audio to PCM wav and use that as the audio source in TMPGEnc. If it is still out of sync, use the time warp effect in Goldwave to stretch the audio so it matches the length of the mpeg video, save as wav, convert to mp2 with FFMPEGgui, then mux with the video using TMPGEnc's MPEG Tools.

I've done that, but it doesn't help. TimeWarp is something I have been doing anyway because I was trying to do an NTSC -> PAL conversion as well, but it doesn't work. The sync issue is not a progressive one, it is fixed and noticeable right from the first frame. Even doing the conversion without an NTSC -> PAL conversion doesn't work either. Keeping everything as NTSC still results in audio sync mismatch. I need something that will tell TMPGEnc to keep the audio preload as it is in the original DivX file because that plays fine.
