Dynamic audio delay while encoding

[dalime]

Not sure if this if the right forum or if anyone can even help but here's the issue. I'm encoding a Bluray source to WMV. The Bluray I have only has a Japanese audio track, but I also have the same film on DVD with English DD. So I stripped the audio off the DVD and are encoding them together with TMPGenc. The problem is that the audio get slower as the film progresses. At start i'm delaying at 2000ms and by the end of the film it's at 2400ms. Is there anyway, with TMPGenc or any other tool, to increse the delay while its encoding?
Thanks for the help.

This is the wrong sub forum, should go in avisynth or audio encoding.

What it sounds like is that the frame rate for your audio and video aren't in sync. Perhaps the Blu-ray is playing @ 25 fps, and your DVD @ 23.976 fps. Or maybe even you have a mismatch in the frame rates by accident. Any one of these will cause your audio to go out of sync with the video.

Thanks Sage. That was it.
So I'm now trying to use BeSweet to adjust the ac3 to match the framerate of the video file, but none of the Soundtouch switches are working. Namely the framerate adjustment without touching the pitch (-r).
There's no real clear cut direction on what to do or where to put the soundtouch source from the BeSweet site, so I assume you just unpack it to the root directory where BeSweet is.
Also seems that there should be a .dll and there isn't.
Went to the Soundtouch site and starting to read about compiling a build and am getting out of my league here.
Simply put, how do I get Soundtouch to jive with BeSweet? Is there something I'm missing?
Thanks.
