Hi

I have a DVD that has 2 audio streams: 6ch AC3 (which I guess is the dolby 5.1 track) and 2ch LPCM. I'm encoding the video using DVD2AVI/Gordion Knot and for some reason DVD2AVI will not extract the LPCM stream, although if i try the ac3 stream it works fine. I don't have a 5.1 audio setup so the 2ch audio is what I need: does anyone know if this is a problem with dvd2avi or the ripping software (i'm using DVD Decrytper for the ripping)?

On the other dvds i've ripped it's always been 2ch ac3 audio, but now i've come across this LPCM format, and can't get it.

Alternatively. is it possible to downmix the 5.1 stream to it's 2 channel equivalent?
