Andy, are you saying that the grooves of an lp can contain 4 discreet channels? I've read for decades that the two sides of a record groove can only handle enough information for two discreet left and right front channels plus the left minus right surround channel, as opposed to a DVD-Audio, SACD, or Blu-ray disc that can do full 5 or 5.1 discreet channels.
