Alright, I reformatted my computer a few days ago and now I'm having problems encoding from an AAC source to anything else. I have the latest AVI Synth installed, VirtualDub, MeGUI, Lame, Winamp, Nero AAC, etc.

Basically I'm trying to encode the audio from a RAW anime source. When I say RAW I mean a captured video that's been encoded once. The problem happens when I try to use MeGUI to use the video's audio source (AAC) and encode it into either Lame MP3, Winamp AAC, or Nero AAC.

Here's the errors from MeGUI I get with Lame MP3, Winamp AAC, and Nero AAC respectively.

Nero AAC:
--[Error] An error occurred
---[NoImage] Exception message: The pipe has been ended.
---[NoImage] Stacktrace
----[NoImage] at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
----[NoImage] at System.IO.FileStream.WriteCore(Byte[] buffer, Int32 offset, Int32 count)
----[NoImage] at System.IO.FileStream.Write(Byte[] array, Int32 offset, Int32 count)
----[NoImage] at MeGUI.AviSynthAudioEncoder.encode()
---[NoImage] Inner exception: null

Winamp AAC:
--[Error] An error occurred
---[NoImage] Exception message: Abnormal encoder termination -4
---[NoImage] Stacktrace: at MeGUI.AviSynthAudioEncoder.encode()
---[NoImage] Inner exception: null

Lame MP3:
--[Error] An error occurred
---[NoImage] Exception message: The pipe has been ended.
---[NoImage] Stacktrace
----[NoImage] at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
----[NoImage] at System.IO.FileStream.WriteCore(Byte[] buffer, Int32 offset, Int32 count)
----[NoImage] at System.IO.FileStream.Write(Byte[] array, Int32 offset, Int32 count)
----[NoImage] at MeGUI.AviSynthAudioEncoder.encode()
---[NoImage] Inner exception: null

And when I try to convert it to WAV through Vdub with this script:
ffmpegsource("MyVideo.mp4", atrack=-1)
tfm(order=-1).tdecimate()

It only saves the first 6 minutes.

Anyone know why I'm getting these errors and can't encode from an AAC? If it's not an AAC I can encode it, I can even encode it into AAC if it's not an AAC source.
