Converting Horse Feathers DVD to MP4 - audio plays too fast

[wkrick]

I'm trying to convert one of my DVDs to MP4 so I can load it on my Zune.
I'm using Fair Use Wizard 2.11b to do the conversion.
The resulting MP4 has audio that plays roughly twice as fast as it supposed to (sounds like chipmunks).
I've encoded many other DVDs with FU2 and never had this problem so I'm thinking it must have something to do with the disc.

Here's some details about the DVD itself...

Title: Horse Feathers
Company: Universal
Region: 1
Released: 1998
Catalog Number: ID4289USDVD
ISBN: 0014381428926


The only thing I can see that's different about this disc is this note on the packaging and disc...

"This disc is encoded with an uncompressed PCM soundtrack"

When opening the disc in DVDShrink 3.2, it reports the audio stream as...

"LPCM 1-ch English"

...so I guess it's an uncompressed mono audio stream.


Any thoughts?

It should not make any difference. I would suggest the following :

1. Rip with a recent ripper - DVDFab HD Decrypter - to ensure that there is no leftover copy protection giving you grief. DVD Shrink and DVD Decrypter are way out of date.
2. Try a different encoder. I have been using XmediaRecode for my DVD to MP4 conversions and find it does a very good job.

It turns out that the mono audio channel WAS the problem.

I suspect that Fair Use Wizard was endoding the audio as if it was a stereo stream, splitting the mono data between the two channels and making it play twice as fast (chimpmunk audio).

Here's the steps I took to arrive at a proper MP4...

1) Rip the DVD to my hard drive as files (VIDEO_TS) using DVDDecrypter

2) Split the audio and video streams using PGCDemux

3) Convert the original audio (a mono WAV) to stereo using dbPowerAmp

4) Combine the original video stream and the new stereo WAV into files (VIDEO_TS) using Muxman

5) Convert VIDEO_TS files back into ISO using DVDShrink (I had to change the settings to DVD9 since the new ISO was too big for a DVD5 now that the audio track is twice as large, and I didn't want it to re-encode the video)

6) Create MP4 using Fair Use Wizard from the DVD9 ISO just created

The problem is with FUW, not the audio. The audio is perfectly legal, so if FUW can't handle it, that it FUW's problem.
