Sound wuality problems converting DV AVI to Mpeg2

[caernavon]

I'm trying to author a DVD from a movie my mother took on her vacation. I capture the video with WinDV, and the resultant AVI files look and sound fine. I set the discontinuity threshold to 1, because I only want 1 clip, and I have the "type" set to 1 (I also tried setting it to 2, but there seemed to be no sound in the resultant AVI).

The problem is once I've converted the AVI to Mpeg2 with TMGPEnc the audio sounds like it has dropped several octaves. It's not out of synch; it's just low.

Should I have set it to capture type-2 AVI in WinDV? Or is the problem with TMGPEnc? This is the first time I've seen anything like this. Thanks for any suggestions anyone has.

A few things.
To ensure a single large file set the Discontinuity Threshold to 0 and the Max AVI size to over 110000 (that's a little over an hour). Do not use device control (make sure that unlabeled checkbox is not checked). Then manually start playing the camera then click capture.
I don't think TMPGEnc likes Type1 but I don't use it, so I can't confirm. You can convert your Type1 file to Type2 by opening it in VirtualDub, setting the Video and Audio to Direct Stream copy, and save to AVI.

My version of TMPGEnc Plus encoder won't accept Type 1 DV. One Type 1> Type 2 converter: Ulead DV Type 1 to DV Type 2 Converter

I don't use TMPGEnc encoder for audio encoding. I open the DV in VirtualDub Mod (By adding the Panasonic DV Codec) and save out the audio as a WAV, then use ffmpeggui to convert the audio to AC3. I add the MPEG-2 encoded video and the AC3 audio when I author with TMPGEnc DVD Author. Then burn with ImgBurn.

The newer versions of VirtualDub will accept Type 1, but VDM needs Type 2. Virtual Dub Mod is also a good DV editor and has quite a few video filters available if needed. But do your editing before separating the audio from the DV file. If you need a audio editor for WAV or MP3 to clean up the audio, Audacity is freeware and works well.
