Audio problems

[kakomu]

I'm unable to extract the audio from my captured AVI files. I installed the panasonic DV codec. I used DVIO and WinDV to make 10 second clips of a movie I just shot. One of Type-1 and one of type-2.

In MPC:
Type-1 will play in MPC with audio just fine.
Type-2 will play in MPC but without audio.

In VDUB mod:
Type-1 gives me an error about audio. Doesn't show up in streams
Type-2 has an audio track, but when I try to demux it, it's really small and has no audio

As an AVS file in VDUB Mod
Type-1 will have an audio file and will be able to extract, but the audio file that's extracted is slown down by 1/2 speed or so.
Type-2 will do the same as the AVI.

I'm rather stumped. I'm not sure how to go about extracting the audio since none of the above methods worked correctly.

I looked in the file info for the Type-2 AVI and the audio is about .5 seconds long and listed as 1024kbps. It looks as though neither DVIO or WinDV are actually capturing the audio.

Update: I took a type-1 AVI that played fine in MPC and used a program to convert the file into a Type-2 AVI. The resulting avi had the same .5 seconds of audio.

update: I used Ulead's DV converter software. It produces a working Type-2 avi file, but the audio has a horrible ringing sound.
Canopus's DV converter worked. However, that doesn't explain why so many other methods didn't work...

Does anyone know why I may not have been able to create a working Type-2 avi file with WinDV and DVIO?

Did you use 32 kHz Audio?

No, I believe I used 48khz/16-bit audio.

I just set the camera to 12-bit and extracting a type-2 avi worked this time. Is 16-bit/48khz out of spec or do I need special software to pull such audio from the tape?

You have a tape of it? Why not do a re-recording or have you tried this already?

How are you capturing it and with what hardware?

When I said I set it to 12-bit, I meant that I set the camera to record at 12-bit and recorded a clip which captured correctly.

No, I can't re-record, since the tape was of me doing a bit of work (taking apart an LCD monitor).

I'm working from a Canon optura 50, through IEEE 1394 and using DVIO and WinDV as my capture programs.

So, as a recap: recordings I made with 16-bit audio don't capture correctly with type-2, but recordings I made with 12-bit audio do capture correctly.

Again, why would the capture programs capture 12-bit audio fine, but not 16-bit audio?

Usually it's the other way round: sometimes there are problems with 32 kHz audio, but not with 48 kHz.
