I have downloaded an AVI file containing one video stream and two audio streams.

GraphEdit gives me this information:

AVI file -> AVI splitter.
AVI splitter (stream 00) -> DivX Decoder Filter -> Video renderer.
AVI splitter (stream 01) -> MPEG layer-3 decoder -> (input 01) Morgan stream switcher.
AVI splitter (stream 02) -> MPEG layer-3 decoder 0002 -> (input 02) Morgan stream switcher.
Morgan stream switcher -> Default directsound device.

How can I save the video stream as file 1, first audio stream as file 2 and second audio stream as file 3?

Vdub does not seem to work. Saving as WAV gives me a file where I can only hear the first audio stream. Does this WAV contain both audio streams even though I can only play the first stream with Windows Media Player and RealOne Player? If yes, how do I split the WAV into the two audio streams?

Best regards,
