With mencoder, I use mencoder -oac copy to keep the AC3 digital surround
when encoding from DVDs. Correct me if I'm wrong, but because Dolby
ProLogic (Surround) audio is matrixed in with the left and right
channels, it'll keep the surround information even after you re-encode
the left and right channels with lame (in mencoder)?
