48K avi audio -> wav -> mpg

[BushyTailedTreeRat]

I'm trying to convert an AVI with a 48K audio track to MPEG for VCD. I tried to extract the audio with VirtualDub, following the guide on this site, but it gives me an error, saying that
"The requested audio compression is not compatible with the input format. Check that the sampling rate and channel count of the input match those of the requested format."

So I extracted the audio with AVI2WAV. But the WAV is at 48K bitrate. TMPGEnc will load it and make an MPG with it, but the audio is "jerky".
So... am I doing something wrong in TMPGEnc? Can I make TMPGEnc work with a 48K WAV soundtrack? Or am I doing something wrong with VDub? Or with AVI2WAV?

BTW, GSpot says that I have all the codecs I need. And the original AVI plays fine in Windows Media Player. But Divx Player 2.0 won't play audio, just video.

Thanks in advance.

Use VirtualDub to get the audio stream (Direct stream copy, Save WAV). This will leave you with a file XXX.wav, but is most likely AC3 or MP3
Rename with apropriate extension, and convert to wav with suitable ??? to wav converter. Use this WAV as input to TMPGEnc. Don't let TMPGEnc resample your audio. Most (S)VCD players can handle 48 kHz audio. If your wont, do the resampling with a dedicated wav editor before passing it on to TMPGEnc.

Thanks mats!
AVI2WAV got me a 48K WAV, so I think that part is done. Tonight I'll try TMPGEnc again without the audio resample and see if my DVD player can handle it.
If it can't, can you recommend a good dedicated WAV editor?

Thanks again.

GoldWave, CoolEdit and Sound Forge are the most common audio editors. Both CoolEdit and GoldWave have a trial period with reduced functionality.
Does the 48k WAV sound OK if you listen to it, before encoding?

uh....
I didn't think to listen to the WAV after I extracted it. I guess that might give me a clue, huh?
I'm at work right now, but I'll check out the WAV tonight and if it's messed up, I'll try extracting it with another program. If it sounds okay, I'll encode it without resampling and see how my DVD player handles it.

Yep, the WAV was bad (doh!)
I saw another thread where someone was having similar problems. Some of the responses recommended Goldwave, so I tried it. Everything worked great from there.

Thanks again!
