Hi All

I looked around 4 - 5 pages in the AAC forums and I could not locate a solution so I apologize in advance if there's an answer here somewhere...:

Using Yamb (w/the mp4box)I de-muxed an .mp4 A/V stream and extracted the raw AAC and another version with the audio only .mp4. But iTunes did not recognize either version.

But if I encoded the .mp4 video file using fre:ac (great product!) or with Switch audio encoder from NCH I was able to play it in iTunes. Obviously this would degrade the audio by one more lossy generation and I would like to avoid it. Am I missing something with Yamb or is there a product that can de-mux the A/V stream and re-package it into an iTunes compatible .m4a file?

I am not an expert so I thought I would ask here. Any pointers would be greatly appreciated. Thanks.
